Tourism visual deception in “check-in tourism”: Value co-creation and co-destruction perspectives

social media has changed the way tourism-related information is generated and disseminated. Research has focused on the benefits of social media for tourism management while ignoring its drawbacks. Using script theory and service-dominant (S-D) logic, this study explores whether visual deception in tourism can lead to value co-creation and co-destruction. We conducted a thematic analysis of 190,000 words of textual data from 29 interviews on xiaohongshu and Weibo and found that tourism visual deception resulted in the dual outcomes of value co-creation and co-destruction by multiple stakeholders involved in a co-participation process. In addition, the study revealed two types of tourism visual deception interactions in check-in tourism: feedback and learning. Each type of interaction has the dual potential for value co-creation and co-destruction, depending on the consistency of the operating scripts. However, script inconsistency does not necessarily lead to value co-destruction. This paper highlights the important role of social media platforms for value recovery. When value co-destruction occurs, social media platforms, bloggers, and tourists actively engage in value recovery and adopt co-recovery strategies to transform value co-destruction into co-creation. Meanwhile, we have discovered that the service restoration mechanism primarily relies on the interplay between service remedies, types of failures, response speed, and tourists' emotions. Our findings provide important theoretical contributions and practical insights for tourism deception research and marketing practice.

Construction and Application of Ecological Remediation Technology for Sandy Soils in Northwest China

This study investigated the impact of three ecological restoration methods: PRS, OLRS, and NRM, on the soil quality and ecological environment of the cold plateau area in northwest Sichuan, China. Over a period of 3 years, these restoration modes were applied, and their effects on soil enzyme activity, organic carbon, and nitrogen were critically analyzed. The results demonstrated that PRS was the most effective restoration method, enhancing soil water content, organic activity, and enzyme content the most, followed by OLRS and NRM, respectively. In the 0~60 cm soil layer, each restoration model was able to improve the vegetation characteristics, and the modification effects were PRS > ORRS > NRM > UMD in descending order. After the restoration, the summer surface temperature decreased from 41.3 °C to 23.1 °C. The average moisture content of the soil increased from 3.11% to 5.86%. The average moisture content of the soil increased from 3.11% to 5.86%, and the bulk density decreased from 1.47 g/m3 to 1.40 g/m3, resulting in a more rational soil structure. This research offers invaluable insights into the nutrient restoration mechanism of sandy lands, emphasizing the significant role of appropriate vegetation restoration measures in ecological restoration. The findings further suggest the potential application of the PRS model for optimal soil repair effects in similar ecological settings.

Geodesic completeness of effective null geodesics in regular space-times with non-linear electrodynamics

We study the completeness of light trajectories in certain spherically symmetric regular geometries found in Palatini theories of gravity threaded by non-linear (electromagnetic) fields, which makes their propagation to happen along geodesics of an effective metric. Two types of geodesic restoration mechanisms are employed: by pushing the focal point to infinite affine distance, thus unreachable in finite time by any sets of geodesics, or by the presence of a defocusing surface associated to the development of a wormhole throat. We discuss several examples of such geometries to conclude the completeness of all such effective paths. Our results are of interest both for the finding of singularity-free solutions and for the analysis of their optical appearances e.g. in shadow observations.

InFaRR: In-Network Fast ReRouting

InFaRR (In-network Fast ReRouting) is an algorithm for fast rerouting in programmable data planes. Implemented in P4, InFaRR is free of additional headers and network state heartbeats. InFaRR has four essential features not jointly found in other recovery mechanisms: Loop prevention, Pushback, Recognition and Restoration and Return to the main route. Tests in standard Fat-Tree and AB Fat-Tree topologies with failures in different scenarios showed positive results when compared to state-of-the-art algorithms in the literature. In scenarios in which the other algorithms were able to recover, InFaRR presented fewer hops to bypass the failure when the Pushback, Loop Prevention and Recognition and Restoration mechanisms were used. In scenarios with multiple failures, InFaRR successfully rerouted where the others algorithms in some cases looped. The mechanism for returning to the main route allows to verify failures in remote links, making it possible to return to the main route without intervention from the control plane. Several evaluations were done comparing the results of InFaRR with the state-of-the art mechanisms, showing the capability of our fast rerouting algorithm in dealing with failures at the line-rate.

Laser based additive manufacturing of tungsten: Multi-scale thermo-kinetic and thermo-mechanical computational model and experiments

Coupling a multi-scale thermo-kinetic and thermo-mechanical model with critical experiments, the present study investigates the role of process parameters on the resulting densification, cracking behavior, and microstructural evolution in laser-based powder bed fusion (LPBF) of pure tungsten. Thermal management strategies comprising shorter scan length (1 mm) and/or substrate preheating (873 K) were explored to achieve higher densities and mitigate cracks. A finite element (FE) based thermo-kinetic and thermo-mechanical computational model was developed to simulate the process spanning from the melt pool scale to the component level. FE simulations indicated pronounced heat accumulation with reduced scanning lengths. Such increased heat accumulation resulted in melt pools with larger dimensions (width and depth) and more favorable rheological characteristics resulting in printed tungsten parts with higher densities. Using an input laser fluence (ILF) of 28.6 J/mm2 and a shorter scan length of 1 mm, a relative density of maximum 99.2% was achieved, the highest reported value using LPBF in case of pure tungsten. FE simulations indicated nearly 5-fold reduction in thermal gradients and 2-fold reduction in cooling rates associated with the processing conditions corresponding to low degree of cracking (ILFs:28.6 J/mm2 and ILF 15.9 J/mm2 augmented with substrate preheating at 873 K) compared to the processing conditions of high degree of cracking (ILF: 15.9 J/mm2). Further, high ILF samples were characterized by significant extent of in-grain misorientations and low angle boundaries indicating that process induced in-situ restoration mechanisms are operative, thereby potentially aiding in reduction of cracking.

Dynamic recrystallization under hot deformation of additively manufactured 316 L stainless steel

The high-temperature deformation behavior of additively manufactured 316 L stainless steels prepared via the laser powder bed fusion (LPBF) technology was investigated using Gleeble compression testing in a wide temperature range of 473–1273 K under a constant strain rate of 0.001 s−1, perpendicular to the building direction (BD). The softening flow property upon continuous concurrent isothermal heating deformation displayed an excellent thermal stability performance up to the temperature of 873 K, preserving the material strength higher than 600 MPa compared to the room-temperature property of the as-built material. By the gradual increase of testing temperature, the compressive strength of the material was continuously decreased to even <50 MPa at a temperature of 1273 K. After hot compression; all tested specimens were characterized across different regions in terms of deformation substructure evolution and crystallographic texture using electron backscattering diffraction (EBSD) and constitutive analyses. Accordingly, the estimated activation energies based on established constitutive modeling proposed the operation of dynamic recovery (DRV) and discontinuous dynamic recrystallization (DDRX) mechanisms for the hot deformation of additively manufactured 316 L stainless steel below (~9.77kJmol) and higher (~553.23kJmol) than the critical temperature of 873 K, respectively. The competition between strain accumulation and thermal heating induced two different Brass deformation and Goss recrystallization textures below and above this critical temperature by altering the operative dominant dynamic restoration mechanism, with various texture severity depending on the testing temperature.

Hot working processing and microstructure characterisation of as-cast high manganese TWIP steel

ABSTRACT The hot compression of the as-cast Fe-21Mn-0.7C–0.1Si twinning induced plasticity (TWIP) steel was investigated at the deformation temperature range of 950–1100 °C and strain rates of 0.01–5 s−1, using a GleebleTM thermo-mechanical simulator, to determine the hot deformation behaviour and analyse the recrystallisation mechanism. The results showed that the flow curves were characterised by yield-point-elongation (YPE) and dynamic recrystallisation (DRX) as the principal restoration mechanisms. The activation energy (Q) was calculated to be 394.975 KJ mol−1, which implies that the recrystallisation is sluggish in the whole range of the deformation conditions. Furthermore, the processing maps were generated according to the dynamic material model (DMM). The processing map was subdivided into different domains for the microstructural observations. The ideal hot deformation parameters of as-cast high Mn TWIP steel were obtained in the deformation condition range of 1087–1098 °C/10−1.2-10−0.17 s−1. Moreover, the microstructure analysis revealed that the DRX grains were twinned and nucleated through the bulging mechanism at the serrated grain boundaries, accompanied by twin boundaries migration created in the DRX grains by growth accidents, which contributed significantly to the growth of the DRX.

Polyoxidovanadates a new therapeutic alternative for neurodegenerative and aging diseases.

Aging is a natural phenomenon characterized by a progressive decline in physiological integrity, leading to a deterioration of cognitive function and increasing the risk of suffering from chronic-degenerative diseases, including cardiovascular diseases, osteoporosis, cancer, diabetes, and neurodegeneration. Aging is considered the major risk factor for Parkinson's and Alzheimer's disease develops. Likewise, diabetes and insulin resistance constitute additional risk factors for developing neurodegenerative disorders. Currently, no treatment can effectively reverse these neurodegenerative pathologies. However, some antidiabetic drugs have opened the possibility of being used against neurodegenerative processes. In the previous framework, Vanadium species have demonstrated a notable antidiabetic effect. Our research group evaluated polyoxidovanadates such as decavanadate and metforminium-decavanadate with preventive and corrective activity on neurodegeneration in brain-specific areas from rats with metabolic syndrome. The results suggest that these polyoxidovanadates induce neuronal and cognitive restoration mechanisms. This review aims to describe the therapeutic potential of polyoxidovanadates as insulin-enhancer agents in the brain, constituting a therapeutic alternative for aging and neurodegenerative diseases.

Development of microstructural heterogeneities and dynamic restoration activity during ring rolling of Ti-6Al-4V alloy and its tensile response

Ring rolling is one of the advanced metal forming processes to produce seamless rings. Being a bulk forming process, inhomogeneity in the distribution of strain and temperature can be anticipated in the ring cross-sections. This, in turn, is expected to influence the evolution of microstructure and correspondingly the mechanical properties. Processing of Ti‐6Al‐4V alloy is equally challenging because of its poor thermal conductivity and formability with a limited deformation window. Ti‐6Al‐4V preforms were rolled at elevated temperature under two different main roll feed rates to obtain approximately 30 % deformation in the lab scale ring rolling facility. The evolution of microstructure, including crystallographic texture, was examined as a function of feed rate at different locations of the rings using electron backscattered diffraction (EBSD) technique, and subsequently the tensile response of the rings at selected locations was evaluated at room temperature. The effect of feed rate was found to be marginal on the microstructure evolution; however, there were substantial differences in grain sizes and texture evolution in the regions from inner to outer side of the ring cross-section. Coarse grains were seen at centre region of the ring, while fine grains were present in the region near inner diameter of the ring. Surface regions which experienced more deformation developed basal texture, while the interior regions possessed shear texture after ring rolling. Detailed analysis of the EBSD results suggested orientation dependent continuous dynamic recrystallization as the restoration mechanism in the alloy during ring rolling. The effect of feed rate on the tensile response of the ring rolled alloy was found to be negligible; however, the tensile strength of the ring varied with the location, in accordance with the microstructural heterogeneity. This study provides proper basis for quality control and better understanding for technical guidance required for designing the ring rolling process, specifically for Ti‐6Al‐4V alloy.

The impacts of industrialization on welfare of expropriated households in Sabata Town of Ethiopia

Land acquisitions for expansion of industries through expropriation have affected means of income generation of evicted people in Ethiopia. The data was analyzed using descriptive statistics and endogenous switching regression. Results showed that the expropriated households have lower total income and higher personal expenditures than the non-expropriated household’s. Besides, the total income of the expropriated households was significantly lower than that of the non-expropriated households. Thus, there should be a restoration mechanisms through the implementation of livelihood improvement fund; provision of share stock from company; training of expropriated people at financial accounting and management system, provision of infrastructure and service facilities, and creation of safe environment for the society.

Effect of compression bonding temperature on the strength-ductility balance of AA7075 alloy

In this study, the effect of compression bonding temperature on the microstructure and strength-ductility balance of AA7075 alloy was investigated. The results showed that dynamic recovery (DRV) was the dominant restoration mechanism in the compressed samples at 25, 100, 200, and 300 °C decreasing the dislocation density of elongated grains, while dynamic recrystallization (DRX) was predominant in the compressed sample at 400 °C forming fine equiaxed grains. By increasing the compression temperature, the bonding quality is improved. Several MgZn2 peaks could be observed in the diffraction pattern of the processed sample at 400 °C, confirming the occurrence of overaging. By increasing the compression temperature from 25 °C to 300 °C, the texture parameter of {200} (as recrystallization texture) was continuously reduced from 2.13 to 1.11, while the texture parameter of {220} (as deformation texture) was continuously enhanced from 2.09 to 4.91 due to the higher height reduction in the larger compression temperature. By further increasing the compression temperature to 400 °C, the texture parameter of {200} is significantly increased from 1.11 to 3.21, while the texture parameter of {220} is remarkably decreased from 4.91 to 0.83 owing to the occurrence of DRX. By increasing the temperature from 25 °C to 400 °C, the hardness of both AA7075 and pure aluminum layers was decreased due to the intensifying recovery and recrystallization. After the compression bonding, no evidence of the Portevin Le Chatelier was found and the stress-strain curves exhibited normal behavior. With increasing the temperature from 25 °C to 400 °C, yield and ultimate tensile strength were decreased from 672.7 MPa and 689.8 MPa to 187.4 MPa and 374.9 MPa, respectively, while the total elongation and energy absorption were increased from 6.2% to 40.6 J/cm3 to 33.7% and 108.1 J/cm3, respectively. At the early stage of plastic deformation, the strain hardening rate of the compressed sample at 400 °C was significantly lower than that of other compressed samples. However, when the ε reaches 0.09, the strain hardening rate of the sample became larger than that of other processed samples due to the recovery of the strain hardening rate (RSHR) phenomenon at stage III in the compressed sample at 400 °C. The fracture features of all samples were characterized by dimples and cleavage facets, indicating the occurrence of a mixed ductile/brittle mode of fracture. However, by increasing the compression temperature, the dimpled portion of the fracture surface was increased. The dimples were coarsened when the compression temperature increased owing to the softening of samples as well as coarsening of MgZn2 precipitates at higher temperatures.

Short-term legacy effects of long-term nitrogen and water addition on soil chemical properties and micro-bial characteristics in a temperate grassland.

Nitrogen deposition and summer precipitation in eastern Inner Mongolia are predicted to increase in recent decades. However, such increases in nitrogen inputs and precipitation may not be continuous under the future new patterns of global change, with the direction and magnitude of which may change or weaken. The legacy effects of nitrogen and water addition after cessation on ecosystems are still unclear. Based on a 13-year nitrogen and water addition experiment in temperate grassland of northern China, we examined the short-term (2 years) legacy effects of historical nitrogen and water addition on soil physicochemical properties and microbial properties after the cessation of nitrogen and water addition in the 14th year. The results showed that the positive effects of historical nitrogen addition on most of soil nutrient variables diminished after two years of cessation, including ammonium nitrogen, nitrate nitrogen, dissolved organic carbon and nitrogen, and Olsen-P concentrations. In contrast, there were legacy effects on soil microbial characteristics. For example, the historical nitrogen input of 15 g N·m-2·a-1 reduced microbial biomass carbon, respiration, and alkaline phosphomonoesterase activity by 73.3%, 81.9%, and 70.3% respectively. It implied that microbial parameters restored slowly in comparison with soil nutrients, showing a hysteresis effect. Results of Pearson's correlation and redundancy analysis showed that the legacy effects of historical nitrogen addition on microbial parameters could be attributed to the negative effects of nitrogen addition on soil pH. Historical water addition showed significant legacy effects on soil pH, ammonium nitrogen, dissolved organic carbon and nitrogen, respiration, and soil enzyme activities, which significantly interacted with historical nitrogen addition. These results are of great significance to predict the changes in grassland ecosystem functions and services under the local environmental improvement conditions, and to reveal the restoration mechanism of degraded grassland.

Biomimetic Platelet Nanomotors for Site-Specific Thrombolysis and Ischemic Injury Alleviation.

Due to the mortality associated with thrombosis and its high recurrence rate, there is a need to investigate antithrombotic approaches. Noninvasive site-specific thrombolysis is a current approach being used; however, its usage is characterized by the following limitations: low targeting efficiency, poor ability to penetrate clots, rapid half-life, lack of vascular restoration mechanisms, and risk of thrombus recurrence that is comparable to that of traditional pharmacological thrombolysis agents. Therefore, it is vital to develop an alternative technique that can overcome the aforementioned limitations. To this end, a cotton-ball-shaped platelet (PLT)-mimetic self-assembly framework engineered with a phototherapeutic poly(3,4-ethylenedioxythiophene) (PEDOT) platform has been developed. This platform is capable of delivering a synthetic peptide derived from hirudin P6 (P6) to thrombus lesions, forming P6@PEDOT@PLT nanomotors for noninvasive site-specific thrombolysis, effective anticoagulation, and vascular restoration. Regulated by P-selectin mediation, the P6@PEDOT@PLT nanomotors target the thrombus site and subsequently rupture under near-infrared (NIR) irradiation, achieving desirable sequential drug delivery. Furthermore, the movement ability of the P6@PEDOT@PLT nanomotors under NIR irradiation enables effective penetration deep into thrombus lesions, enhancing bioavailability. Biodistribution analyses have shown that the administered P6@PEDOT@PLT nanomotors exhibit extended circulation time and metabolic capabilities. In addition, the photothermal therapy/photoelectric therapy combination can significantly augment the effectiveness (ca. 72%) of thrombolysis. Consequently, the precisely delivered drug and the resultant phototherapeutic-driven heat-shock protein, immunomodulatory, anti-inflammatory, and inhibitory plasminogen activator inhibitor-1 (PAI-1) activities can restore vessels and effectively prevent rethrombosis. The described biomimetic P6@PEDOT@PLT nanomotors represent a promising option for improving the efficacy of antithrombotic therapy in thrombus-related illnesses.

Role of Lake Aquatic-Terrestrial Ecotones in the Ecological Restoration of Eutrophic Water Bodies.

Freshwater lake eutrophication is a global concern causing adverse effects on aquatic ecosystems. The degradation of lake aquatic-terrestrial ecotones, which are the transitional zones between terrestrial and water ecosystems, contributes to eutrophication. These ecotones play vital roles in nutrient cycling, runoff control, biodiversity conservation, and habitat provision. In the past three decades, the research on lake aquatic-terrestrial ecotones has focused on techniques for managing contaminants and runoff purification. This paper reviews the recent studies on the restoration ability of eutrophic water bodies in lake aquatic-terrestrial ecotones in recent years regarding three aspects: the establishment, restoration mechanism, and improvement of restoration function. In addition, ecological factors such as lakeshore height, water level, surface runoff, shallow groundwater level, and rainfall intensity have impacts on the restoration capacity of lake aquatic-terrestrial ecotones.

Rescuing the Golgi from heat damages by ATG8: restoration rather than clean-up

High temperature stress poses significant adverse effects on crop yield and quality. Yet the molecular mechanisms underlying heat stress tolerance in plants/crops, especially regarding the organellar remodeling and homeostasis, are largely unknown. In a recent study, Zhou et al. reported that autophagy-related 8 (ATG8), a famous regulator involved in autophagy, plays a new role in Golgi restoration upon heat stress. Golgi apparatus is vacuolated following short-term acute heat stress, and ATG8 is translocated to the dilated Golgi membrane and interacts with CLATHRIN LIGHT CHAIN 2 (CLC2) to facilitate Golgi restoration, which is dependent on the ATG conjugation system, but not of the upstream autophagic initiators. These exciting findings broaden the fundamental role of ATG8, and elucidate the organelle-level restoration mechanism of Golgi upon heat stress in plants.

Protective effect of restorative possibilities on cognitive function and mental health in children and adolescents: A scoping review including the role of physical activity

BackgroundThe exposome approach can be a powerful tool for understanding the intertwining of social, physical, and internal influences that shape mental health and cognitive development throughout childhood. To distil conceptual models for subsequent analyses, the EU-funded project Early Environmental quality and Life-course mental health effects (Equal-Life) has conducted literature reviews on potential mediators linking the exposome to these outcomes. We report on a scoping review and a conceptual model of the role of restorative possibilities and physical activity.MethodsPeer-reviewed studies published since the year 2000 in English, on the association between the exposome and mental health/cognition in children/adolescents, and quantitatively investigating restoration/restorative quality as a mediating variable were considered. Database searches were last updated in December 2022. We used an unstructured expert-driven approach to fill in gaps in the reviewed literature.ResultsFive records of three distinct studies were identified, indicating a scarcity of empirical evidence in this newly developing research area. Not only were these studies few in numbers, but also cross-sectional, lending only tentative support to the idea that perceived restorative quality of adolescent's living environment might mediate the association between greenspace and mental health. Physical activity emerged as a mediator leading to better psychological outcomes in restorative environments. We provide a critical discussion of potential caveats when investigating the restoration mechanism in children and propose a hierarchical model including restoration, physical activity, and relational dynamics between children and their environment, including social context, as well as restorative environments other than nature.ConclusionsIt is justified to further explore the role of restoration and physical activity as mediators in the association between early-life exposome and mental health/cognitive development. It is important to consider the child perspective and specific methodological caveats. Given the evolving conceptual definitions/operationalizations, Equal-Life will attempt to fill in a critical gap in the literature.

Hot deformation behavior and processing map development of Mg/Al2O3 composite: A case study of extrusion ratio effects

The hot deformation behavior of 2.5 wt.% submicron alumina reinforced magnesium composite manufactured by a new casting method was examined to assess the impact of extrusion ratio and initial microstructure on the hot workability of Mg/Al2O3 composite. The thermomechanical experiments were performed at strain rates from 0.001 s−1 to 0.05 s−1 and the temperature ranging from 523 K to 673 K. The processing map was developed using power dissipation efficiency in terms of temperature and strain rate. Results revealed that the higher extrusion ratio yields finer grain size and a more homogenous distribution of alumina particles resulting in lower flow stress and activation energy. Stable regions with more power efficiency (57%) and less instability were observed in materials that experienced higher strain. Based on the microstructural observation, dynamic recrystallization as the main restoration mechanism occurred at composite with a higher extrusion ratio and finer grains in all conditions. It was deduced that the enhanced workability of fine-grain material is confirmed by steady flow stress and safe zones of the processing map. It was also revealed that twinning–twinning intersection and flow localization are the main reasons for unstable flow in both samples with unlike grain sizes.

Analyzing anthropogenic impact on Ibanda-Makera natural forest in Kirehe district

Human pressure from farming activities on marginal lands, and on forest reserves in particular, have resulted in the loss of the large number of hectares of natural forests. This problem also occurred on Ibanda-Makera natural forest locating in Kirehe District, Eastern Province of Rwanda. In this study, we study anthropogenic impact on Ibanda-Makera natural forest. The identification of anthropogenic activities affecting Ibanda-Makera natural forest was done; their impacts on forest was analyzed; and the level of degradation in terms of forest cover of Ibanda-Makera was determined. The study adopted both qualitative and quantitative methods to collect data from a sample of 97 individuals in the target population of 3,330 people. Data were collected using questionnaire, interview guide techniques and documentation. Through SPSS analysis, Pearson correlation between anthropogenic activities and forest degradation, the results showed that people have an understanding on factors leading to the forest degradation and that land use activities surround the Ibanda-Makera area were not in way of protecting forest as priority. Change detection from analysis of 2012, 2017 and 2022 images under supervised classification using remote sensing data of Ibanda-Makera natural forest, showed spatial variation where degradation is high between 2012 to 2017 and low between 2017 to 2022 expressing that between 2017 to 2022 under some environmental guidelines the damaged area moved to the restoration mechanisms. The recommendation to government, regular monitoring of forest boundaries to prevent potential damages that may occur on the forest and set a local system of protection.

Metamodelling the hot deformation behaviour of titanium alloys using a mean-field approach

During the thermomechanical processing of titanium alloys in the β-domain, the β-phase undergoes restoration phenomena. This work describes them by a mean-field physical model that correlates the flow stress with the microstructural evolution. To reduce the computational time of process simulations, metamodels are developed for specific outputs of the mean-field physical model using Artificial Neural Network (ANN) and Decision Tree Regression (DTR). The performance of the obtained metamodels is evaluated in terms of the coefficient of determination (R²), the root-mean-square error (RMSE), and the mean relative error (MRE). No significant difference was observed between R2training and R2testing, meaning that all the metamodels correctly generalise the overall behaviour of the outputs for a wide range of inputs. The evolution of the metamodel outputs is compared with the model predictions in two different situations: 1) at a constant strain rate and temperature, and 2) during Finite Element (FE) simulations of the hot deformation of a hat-shaped sample, where temperature and effective strain rate vary at each element during deformation. The evolution of the outputs at constant and non-constant strain rates and temperature demonstrated the robustness of the metamodels in predicting the heterogeneous deformation within a workpiece. The computational time required by the metamodels to calculate selected outputs can be more than 100 times less than that of the model itself at a constant strain rate using MATLAB® and up to 19% less when coupled with FE simulations. The simulation results combined with microstructural analysis are used to visualise the different restoration mechanisms occurring in different regions of the hat-shaped sample as a function of the local thermomechanical history. The changes in strain rate and temperature during deformation influence the evolution of the wall dislocation density and the immobilisation rate of mobile dislocations at subgrain boundaries, leading to different kinetics of microstructure evolution.
