Study of meta-dynamic recrystallization behavior of GH5188 superalloy

Cobalt-based superalloys have good service performance in environments where nickel-based superalloys cannot work. A number of the studies focused on mechanical properties, microstructure evolution and hot deformation characteristics, but studies of meta-dynamic recrystallization (MDRX) behavior remain lacking. The MDRX behavior of GH5188 superalloy was investigated using two-stage hot compression tests. The kinetic model and grain size model were built to better describe the MDRX process. The good agreement between the predicted values and experimental values was verified. The effects of holding time, temperature, strain rate and intervals time on MDRX microstructure evolution were analyzed and discussed. The results show that by descending order of correlation was: intervals time, holding time, temperature and strain rate. The MDRX fraction and grain size increase with the increase of holding time, temperature, strain rate and intervals time. At low temperatures, MDRX grains grew up in the form of bowed grain boundaries. At high temperatures, the growth of MDRX grains was often accompanied by the generation of twinning bands. Twins were formed in the process of grain growth.

Service Quality and Interest Impact on Satisfaction and Loyalty of Agro Tourism Visitors

The agricultural sector is one of the opportunities for improving the economy of local communities. Opportunities will be a challenge for agro-tourism managers in their development. The purpose of this study was to determine the impact of service quality and importance on visitor satisfaction and loyalty. The research method used is a survey method and research sampling using incidental sampling technique to 127 tourists who come to visit. Furthermore, the data is processed using the Structural Equation Modeling (SEM) method with the support of Amos SPSS Version 24. The results show that good service performance can significantly increase visitor satisfaction by 44%. However, it is inversely proportional to the effect of service performance on consumer loyalty directly. Improved service performance can lower visitor loyalty rates by 48%. In addition, increased satisfaction can also have a significant effect on visitor loyalty by 111%. In contrast to service performance and satisfaction, interests do not have a significant effect on visitor satisfaction or loyalty. So that the presence or absence of complete facilities at the research location does not guarantee that visitors will feel significant satisfaction and loyalty.

Thermal insulation TiN aerogels prepared by a combined freeze-casting and carbothermal reduction-nitridation technique

With the rapid development of energy sources and aerospace engineering, high-performance thermal insulation materials with multiple functions are attracting more and more attentions. Non-oxide ceramic aerogels have application potential in thermal insulation under harsh conditions owing to their good thermal insulation performance and chemical stability. In this work, TiN aerogels were prepared by a combined freeze-casting and carbothermal reduction-nitridation method utilizing TiO2 and chitosan as raw materials, at 1473 K for 3 h, with a C/TiO2 molar ratio of 3/1. They showed a specific surface area of 167 m2/g and ultralow density of 0.07 g/cm3 (the relative density of 1.3 %). Their thermal conductivity value was only 0.166 ± 0.0054 W/(m K at 673 K (TiO2 solid content of 5 wt%). Moreover, the prepared aerogels possessed reasonably high mechanical strength and good high-temperature service performance, suggesting that they can be used under high-temperature conditions as an insulation material.

Enhanced Hot Workability of Ti–46Al–4Nb–0.1B Alloy by Introducing Adjustable β Phase via Elemental Powder Metallurgy

TiAl‐base alloys are a kind of promising materials for high‐temperature applications. The β phase existing in TiAl alloy can improve the hot workability, but deteriorates the creep properties. Preparing a β phase‐containing TiAl‐base alloy to enhance the hot workability before hot deformation and eliminating the β/B2 phase by postheat treatment to improve the service performance is a good strategy. Herein, a significant volume fraction of β phase is obtained in the Ti–46Al–4Nb–0.1B alloy by the elemental powder metallurgy (EPM), and the β/B2 phase is eliminated by the subsequent heat treatment. The results demonstrate that the microstructure of the EPMed Ti–46Al–4Nb–0.1B alloy predominantly consists of α2/γ lamellar colonies, equiaxial γ grains, and some randomly distributed β phase and σ‐Nb2Al phase. The β/B2 phase formed at the Nb‐enriched regions is caused by insufficient diffusion. The EPMed Ti–46Al–4Nb–0.1B alloy has a relatively low thermal deformation activation energy (Q, 410 kJ mol−1), showed a well hot workability. The existence of the β phase is advantageous to harmonize the deformation of α2/γ lamellar grains and to improve the deformability of the TiAl alloy. The subsequent heat treatment can eliminate the Nb‐enriched regions and the B2 phase to ensure good service performance.

Exploring the strength and ductility improvement of Cu–Al alloys

Synchronous improvement of the strength and ductility for metallic materials is an everlasting object as the good service performance. In this study, the yield strength (σYS) and uniform elongation (εUE) of Cu-Al alloys with three Al contents, nine grain sizes induced by the controlled annealing treatment, and three gradient structures induced by surface spinning strengthening (3S) treatment were explored. Results show that the σYS and εUE may be enhanced synchronously by increasing Al content from 5Al, 8Al to 11Al, while the σYS decreases and εUE increases when increasing grain size from ultra-fined grain, fine grain to coarse grain, and the σYS increases obviously and εUE decreases slightly by constructing the gradient layer. The trade-off relation between strength and ductility is broken through by increasing Al content, however cannot be broken through by controlling grain size, and cannot be directly broken through by constructing gradient structure. In addition, the Cu-Al alloys with the high Al content, fine grain and gradient layers obtain the superior combination of strength and ductility, and the reason is that the solid-solution strengthening, boundary strengthening and work hardening are combined together. Inspired by these, the composition design, grain size regulation, and gradient structure construction may be considered as the three feasible approaches to enhance the strength and ductility of metallic materials.

Seismic behaviors of precast assembled bridge columns connected with prestressed threaded steel bar: Experimental test and hysteretic model

Three 1/10-scale bridge pier specimens were tested under quasi-static test. The specimens included two precast specimens (PC1 and PC2) and one cast-in-place reference specimen. The two precast bridge pier specimens were connected with prestressing threaded steel bar and steel flange at the connection between precast pier column and the foundation, and non-socket assembly scheme and socket assembly scheme are adopted, respectively. They were tested to verify the seismic performance of prefabricated piers connected by prestressed threaded steel bars and steel flanges and study which assembly scheme is better for non-socketed and socketed piers. The results show that the prefabricated pier with the combination of the prestressed threaded steel bars and steel flange has higher cracking load and smaller residual displacement, which indicates that it has good service performance and good self-resetting ability. Compared with the non-socket assembly scheme, the socket assembly scheme is superior due to its higher ductility, higher overall initial stiffness, and higher energy dissipation capacity. Therefore, the prefabricated assembled pier with the socket connection scheme of the combination of the prestressed threaded steel bars and steel flange has good service performance and seismic performance. After that, a hysteretic model for the precast assembled columns was proposed, which has a good agreement with the test results.

The distribution regularity of residual stress on a metal surface after laser shock marking

A metal material surface marking method was developed based on the theory that a larger thickness of the absorption layer can attenuate a laser-induced shock wave. The introduction of surface residual compressive stress is the main feature of this new marking method, which is different from the traditional mechanical processing marking method and is also the key factor leading to the good service performance of the metal material surface. After the laser shock marking (LSM) treatment, the residual stress at different positions on the metal surface was measured, and the change in distribution trend of residual stress and microstructure in the laser shock-treated region was discussed. The results show that for two different marking patterns, the expected deformation areas have a remarkable residual compressive stress distribution, and the relatively large full width at half maximum (FWHM) of the X-ray diffraction peak of the expected deformation areas characterizes significant microstructure changes. The microstructure of the edge region of the formed mark shows a sudden change, while the residual stress changes gradually. This change indicates that the surface's severe plastic deformation is directly related to microstructure changes and indirectly related to residual stress changes.

Isothermal Oxidation Behavior of CrSiN Coating Deposited by Magnetron Sputtering at 700°C

CrSiN coatings have been successfully deposited on the surface of GH169 alloy by closed filed unbalanced magnetron sputtering (CFUBMS). The microstructure, chemical and phase composition of the coatings were characterized by SEM, EDS and XRD, respectively. The mechanical properties of the coatings such as microhardness and adhesion strength were measured by indentation method and scratch method, respectively. The isothermal oxidation behavior of CrSiN coating at 700°C was investigated using thermogravimetric analysis. Results show that Cr, Cr2N and CrN coexisted in the dense as-deposited CrSiN coating without Si-containing phases; the coating surface was rough and a small amount of oxide (Cr2O3 and SiO2) was formed on the surface after oxidation at 700°C for 24 hours. The isothermal oxidation result suggested that CrSiN coating possesses excellent oxidation resistance at 700°C. It is considered that the good oxidation resistance of CrSiN coating itself and the formation of dense protectiveCr2O3 and SiO2 films are primarily responsible for the good service performance during the oxidation process at 700°C.

Structural analysis and design of frost resistance function for subgrade of high-speed railway ballasted track in cold regions

According to the technical characteristics of short fixed wheelbase of a high-speed carriage, a subgrade-track integrated space mechanical response analysis model is proposed for trains under the action of biaxial load after the comparison of the stress distribution characteristics of the ballast track subgrade bed structures for high-speed railway under the action of uniaxial load and biaxial load. The loading threshold value(high-cycle long-term dynamic strength) under the circumstance where the cumulative deformation of subgrade structure gradually develops and finally reaches the convergent state, and its relationship with the foundation coefficient K30 were deduced, based on the characteristics of cumulative deformation evolution obtained from the unit structure filling model test under the action of cyclic loading. In view of structure stability and frost resistance requirements of the railway subgrade in cold regions, technical conditions to maintain good service performance of subgrade structure of high-speed railway ballasted track are discussed and analyzed. Study results show that the additive effect manifests itself obviously for railway train bogies under the action of biaxial load than uniaxial load, which has a significant dynamic effect on the subgrade bed bottom and a slight effect on the surface layer. Thus, the adoption of a biaxial load model in the design of a high-speed railway subgrade accurately reflects the vehicle load. Pursuant to the structure design principle, the design method of the subgrade structure of high-speed railway ballasted track is proposed to meet the technical requirements such as structural strength, bearing stiffness and high-cyclic and long-term stability. Technical indicators are obtained for the variation of thickness of the surface layer of reinforced subgrade bed in the double-layer subgrade mode along with the change of K30 at the subgrade bed bottom. The double-layer structure mode of 'closure on the upper layer and drainage on the lower layer' was proposed in o

Influence of Buton Rock Asphalt on the Physical and Mechanical Properties of Asphalt Binder and Asphalt Mixture

In order to study the effect of different rock asphalt contents on the physical and mechanical properties of an asphalt binder and asphalt mixture, the physical and mechanical tests and analysis were conducted. An on‐site case was investigated to verify the effectiveness of rock asphalt‐modified pavement. The results show that the activation treatment can effectively enhance the molecular polarity of Buton rock asphalt. The “wet process” was used to prepare the Buton rock asphalt‐modified asphalt binder, and the high‐temperature performance and aging resistance were significantly improved. The modified asphalt prepared by mixing 30% rock asphalt shows the optimum balance between service performance and segregation. The on‐site full‐scale application of the Buton rock asphalt‐modified asphalt pavement showed the good workability and service performance. This research demonstrated the ability of rock asphalt improving asphalt pavement on multiscales. It is helpful for the broader application of rock asphalt in asphalt pavement.

Impact of Performance Based Contract Implementation on National Road Maintenance Project to Road Functional Performance

The national road network has a significant role in promoting the national economy in Indonesia. But the national road network conditions in general are still not satisfactory although the government continues to improve the technical standards of road maintenance which contributes to the high unit cost of road maintenance. To overcome this classical problem, now the road agencies began to implement alternative road maintenance contracts known as Performance Based Contract (PBC). Successful practice of PBC implementation in various countries indicates that the PBC is able to produce a good road service performance compared with the implementation of in-house system or contract-based input on road maintenance projects. This study aims to measure the impact of PBC implementation on the national road maintenance project in Indonesia with the type of flexible pavement. The impact of PBC is focused on the functional performance, which is measured using a model of IIRMS and expressed in the International Roughness Index (IRI) value. The case study conducted on one of the PBC pilot projects that are in the segment of northern coast of West Java. The results showed that the implementation of PBC for national road maintenance projects proven to ensure the quality and road service performance for the long term.

Chemical wear of Al2O3–MgO–C bricks by air and basic slag

Al2O3–MgO–C (AMC) refractories are used in steelmaking vessels such as ladles, where they are part of the working lining's bottom and walls. Taking into account the conditions during the ladle operation, AMC refractories with high-melt corrosion resistance are required to provide good service performance. Moreover, due to the presence of graphite, AMC bricks should have low susceptibility to attack by oxidant gases. In this paper, the oxidation of commercial AMC refractories by air between 700 and 1400°C and their corrosion by ladle basic slag at 1450°C are examined. The experimental conditions for the chemical evaluation are similar to those to which AMC linings are exposed in some steps of the ladle operation. Differences in the chemical wear caused by both of the reagents among the studied bricks are associated to their differences in composition and microstructural and textural characteristics. In addition, the thermal evolution of each AMC refractory is considered.

Based on the doping of rare earth in metal powders including tungsten carbide, iron and nickel, the cobalt in diamond matrix is entirely with iron and the process route of rare earth doping is indicated. The performance of matrix composites with rare earth elements and free of rare earth elements is measured and the results obtained show that the flexural strength, the hardness and the impact ductility of matrix composites with rare earth elements are improved and the flexural strength increases by 10~62% over that of the composites free of rare earth elements, and the impact ductility by about 5% correspondently. We have successfully studied out the rare-earth diamond tool matrix composites replacing Co with Fe, bearing good practical service performance and low price, and have made corresponding diamond bit.

Nondestructive Testing and Static/Dynamic Loading Detection of a Diseased Fabricated Hollow Slab Bridge

Combined with a repaired project, an old twin decks bridge by simply supported the fabricated prestressed concrete hollow slabs with 16m span was detected in-site. The two decks were built separately in 1987 and 1997 because of economic reasons and demands of traffic flow. The aim of test was to decide whether the bridge can be further used or should be strengthened to meet the demands according to the current design code. Firstly, the damaged and corroded situations of whole bridge were investigated. Then the nondestructive testing methods were adopted to detect the concrete strength and carbonation depth of slabs and piers. The static loading test was conducted to make sure the service behaviors such as crack and mid-span deflection of the whole bridge. Finally, whole bridge was detected by dynamic loading test. The results show that the bridge has enough flexural stiffness to prevent larger deflection and most of slabs are in good service performance. But attacked by the environmental factor such as acid rain, CO2 and winds erosion etc., part of slabs, all railings and sidewalk flats should be replaced. Based on service conditions, the suggestions are given to recover the strength and durability of the bridge. The conclusions would serve as a reference for similar engineering structures.
