Investigation of the impact of the magnetic separation technique on the recovery of non-ferrous metals from Pb-Zn smelter slag

This study offers new approach to the non-ferrous metals? concentration from Pb-Zn slag using a magnetic separation. This technology is more ecological than conventional processes, therefore it may have a substantial influence on the progress of metallurgical slag beneficiation techniques. Physicochemical and mineralogical investigations indicated that Pb-Zn slag is an inhomogeneous with considerable Pb, Zn, Cu, and Ag amounts. Experiments showed that the separated magnetic fraction includes unequal quantities of arsenic, preventing the output from being commercial. Arsenic content was 0.3-32%. Optical and scanning electron microscopy with EDS determined if arsenic can be liberated or easily leached from the resulting material. It was discovered that arsenic is mainly fused with iron-bearing minerals, which are predominantly trapped within amorphous alumino-silicates or intergrowths of alloy grains and glassy phases. This indicates that the produced iron concentrate is viable as a commercial product and in compliance with circularity principles and Green Agenda.

Heat transfer modeling and vacuum brazing of SiCp/ZL102 composites brazed with Al77Cu20Ti3 filler

55% SiCp/ZL102 composite was vacuum brazed utilizing Al77Cu20Ti3 filler. Shear testing was used to investigate the mechanical properties of the joints while SEM, EDS, and XRD were used to analyze the microstructure of the joints and the Al77Cu20Ti3 filler. ABAQUS software was used to examine the brazing process's heat transmission mechanism. Thermodynamics was used to describe how compounds develop at the junction. The findings indicate that the Al77Cu20Ti3 filler alloy's grain size was refined. The filler's solidus and liquidus dropped to 527.13 ℃ and 565.04 ℃, from 540.33 ℃ and 580.07 ℃, respectively. The joint's interface was dense, and its maximum shear strength of 75.38MPa was achieved when vacuum brazed at 590 °C for 30minutes. In the weld, ternary compounds of Ti, Al, and Si were mostly produced. The simulation indicated that throughout the heating process, heat was radiated to the workpiece's surface. First, SiC particles with better thermal conductivity saw a rise in temperature. Lastly, internal heat conduction kept the workpiece's total temperature constant. The base materials conducted heat to the filler, distributing the temperature differential in a circular pattern.

Influence of V/B ratio and rolling treatment on the grain refinement efficacy and anti-fading ability of Al-V-B master alloys

As a promising anti Si-poisoning grain refiner, Al-V-B master alloys have gained increasing attention in the past several years. However, the effect of V:B ratio on the grain refinement effect, as well as the refining mechanism has not been clearly investigated. This work investigates the impact of V:B ratio on microstructures of Al-V-B master alloys and grain refinement efficacy for α-Al grains in AlSi alloys. In addition, the effect of rolling treatment on the agglomeration and sedimentation of Al-V-B master alloys has been investigated. It demonstrates that the V:B ratio significantly affects primary secondary phases within Al-V-B master alloys, with an optimal ratio of 2.33 (Al-4.2 V-1.8B) leading to the finest average α-Al grain size of ~98 μm in the Al8Si alloy. Moreover, rolling treatment further enhances the grain refinement efficacy of Al-4.2 V-1.8B master alloy by dispersing VB2 agglomerates/particles and reducing agglomeration and sedimentation during smelting. Accordingly, the rolled Al-4.2 V-1.8B master alloy reduces the average α-Al grain size to ~75 μm at only 50 % amount of the as-cast Al-4.2 V-1.8B master alloy, improving the grain refinement efficacy by 25 % (75 μm v.s. 98 μm). At the same time, the rolled Al-4.2 V-1.8B master alloy exhibits exceptional anti-fading ability, maintaining a stable grain refinement efficacy for up to 120 min. Cs-corrected transmission electron microscopy (TEM) reveals that VB2 particles act as primary nucleation sites for α-Al grains, with a specific crystallographic orientation relationship: [1 1 2¯ 0] (0001) VB2 || [1¯ 1 0] (111) α-Al. This study provides valuable insights into the design of Al-V-B master alloys with superior grain refinement efficacy and anti-fading ability for AlSi alloys.

Effects of rapid infrared radiation heating on the warping deformation and mechanical properties of selective laser melted Co-Cr dental alloy.

Infrared radiation heating (IRH) technology has been innovatively applied to the annealing of selective laser melted (SLM) cobalt chromium (Co-Cr) frameworks. However, previous studies have not reported the effects of IRH on the warping deformation and mechanical properties of these frameworks. The purpose of this in vitro study was to investigate the effects of IRH on the warping deformation and mechanical properties of dental SLM Co-Cr alloy and to evaluate its potential applications in dental restorations. Two types of specimens, bone-shaped tensile specimens and warping deformation specimens (cantilever beam structures), were fabricated by SLM, followed by annealing using IRH and general furnace heating (GFH). The specimens were divided into 4 groups (n=6) based on the applied heat treatment method and build direction (IRH-XY; IRH-Z; GFH-XY; GFH-Z). The cantilever beam support structure of the warping deformation specimen was cut using wire cutting, and the warping deformation was measured using a digital image correlation optical extensometer. Tensile tests were used to evaluate mechanical properties, with the fracture characteristics being observed using a scanning electron microscope (SEM). A micro-Vickers hardness tester was used to measure the microhardness. The microstructures were analyzed using a metallographic microscope. All data were analyzed using a 1-way ANOVA and the Tukey Honestly Significant Difference test (α=.05). The surfaces of the SLM Co-Cr warping deformation specimens treated with IRH showed slight oxidation, while those treated with GFH exhibited a dark black appearance. No significant difference was found in deformation between the IRH group (0.412 ±0.039 mm) and the GFH group (0.379 ±0.070 mm) (P>.05). The elongation of the longitudinally built specimens was significantly higher than that of their transversely built counterparts (P<.05), while the yield strength showed an opposite trend. The longitudinally built specimens demonstrated ductile fracture characteristics, while the transversely built specimens displayed quasi-cleavage fractures. The specimens treated with IRH exhibited comparable tensile strength and microhardness with the GFH-treated specimens, with no statistically significant differences (P>.05). IRH treatment resulted in finer grains in the SLM Co-Cr alloy. Many fine second-phase particles precipitated from the matrix in the longitudinally built specimens, while few were observed in the transversely built specimens. The SLM Co-Cr specimens treated with IRH achieved comparable warping deformation and mechanical properties with those of the GFH-treated specimens. The IRH technology holds great potential for application to dental restorations.

Principles and Mechanisms of Cryomilling of Metallic Materials: Insights from Recent Studies

Cryomilling (CM) is a vital top‐down process used for creating nanomaterials, offering advantages over traditional mechanical alloying by operating in cryogenic environments. The process minimizes cold welding, enhances particle fracture, and reduces oxidation, leading to ultrafine grains in metallic, alloys, and composite powders. CM is applicable across diverse material systems, including face‐centered cubic, body‐centered cubic, hexagonal close‐packed, and high‐entropy alloys. By examining the effects of CM on various materials with different crystal structures, this review highlights the critical role of processing parameters such as ball‐to‐powder ratio, milling speed, and the use of process control agents. The study further explores how CM enhances mechanical properties like strength and hardness, providing pathways for future research aimed at optimizing efficiency, scalability, and reducing contamination during the milling process.

Effect of LaF3 on the Properties of Pb‐Free Cu‐Based Self‐Lubricating Composites

ABSTRACTA strategy involving the use the rare‐earth compound LaF3 with good lubrication and stability properties as a filler in the preparation of Cu‐based composites was proposed to solve the problem of poor wear resistance in Pb‐free Cu‐Bi materials. The influence and regulatory mechanism of LaF3 content on the mechanical and tribological properties of these composites were studied. The results indicate that LaF3 has a good refining effect on Cu alloy grains, and LaF3 and Bi are distributed in a network along the grain boundaries of the Cu alloy in the material. As the LaF3 content increases, the mechanical properties and friction coefficient of the composite gradually decrease, and the wear rate first declines and then increases. The wear resistance of Cu‐Bi composite containing LaF3 mainly depends on the mechanical support provided by the matrix. When the LaF3 content is higher than 6%, the composite strength is extremely low, and the increase in lubricant content at the friction interface does not play a decisive role in the material wear behaviour. The material wear rate increases with the increase in LaF3 content. Therefore, using 6% LaF3 is recommended to improve the wear resistance of the material and maintain a balance among its mechanical properties, antifriction and wear resistance.

A one-step fabrication of soft-magnetic high entropy alloy fiber with excellent strength and flexibility

Soft-magnetic fibers (SMFs) play a crucial role in energy conversion, transmission, and storage within electronic devices. However, conventional SMFs have poor plasticity and are therefore difficult to withstand long-term tensile, torsional, and shear deformation. A high fraction of grain boundaries could improve plastic deformability of conventional SMFs, but deteriorates the coercivity. This severely limits their applications in flexible electronics and multifunctional components. Herein, we propose a strategy to overcome this dilemma, which is realized by coarsening the grains of a Fe34Co29Ni29Al3Ta3Si2 high entropy alloy (HEA) fiber containing ordered coherent nanoprecipitates with small lattice misfit via a simple one-step in-rotating-water spinning method. This allows to reduce domain wall pinning and improve dislocation mobility. The resultant micron-diameter soft-magnetic HEA fiber has a tensile strength of 674 MPa at 23% elongation, a low coercivity of 8.1 Oe, a moderate magnetization of 116 emu/g at 10 kOe and a high Curie temperature of 770 K.

EFFECT OF Y ON THE MECHANICAL PROPERTIES AND CORROSION RESISTANCE OF AS-EXTRUDED Mg-4Sn ALLOYS

In this study, the effects of Y element on the microstructure, mechanical properties and corrosion resistance of an extruded T4 alloy at room temperature were studied by comparing the as-extruded Mg-4Sn (T4) and Mg-4Sn-1Y (TW41) alloys. The results showed that the second phase of the as-extruded T4 alloy is mainly the Mg2Sn phase, while the ternary MgSnY and Mg2Sn phases mainly precipitate after the addition of Y element. Incomplete dynamic recrystallization of the two alloys occurs during the extrusion process, and the addition of Y element can promote dynamic recrystallization and refinement of the grains in T4 alloy. At room temperature, TW41 alloy has higher strength compared to T4 alloy, with tensile and yield strengths of 228 MPa and 165 MPa, respectively, but the elongation and corrosion resistance are reduced. Grain refinement is believed to play the key role in improving the yield strength of TW41 alloy, while the deterioration of the corrosion resistance of TW41 alloy is mainly attributed to the increase in the grain boundary density caused by grain refinement, accelerating the dissolution of the alloy anode.

Effect of Heat Input on the Mechanical Properties and Microstructures of TIG-Welded AA5052-H32 and AA5083-H111 Plate with ER 5356 Filler Rod

Abstract Dissimilar TIG welding with a constant continuous current was performed on Non-heat treatable Al-Mg alloy plates with ER5356 Filler. These alloys are commonly utilized in the maritime, car, aviation, and chemical processing sectors for structural applications. The creation of porosities, cracking during solidifications, and coarsening of grains in Al-Mg alloys in fabricated TIG weld joints are all prevalent flaws caused by welding heat input supplied by the welding current provided. The Current was regulated from 150A- 180A while maintain a constant travel speed, resulting in a wide range of heat input. To observe the heat input’s force response to the mechanical properties of the joints, tensile tests and Micro Vickers hardness were performed. According to the findings, all of the instances had inferior mechanical properties than the basic alloy. It was observed that employing 170A gave the best mechanical attributes by removing welding faults and resulting in only a 13.5 percent reduction in strength.. At the fusion zone, the grains of specimens manufactured with 170A current are fine. The weld hardness is greatest for specimens fabricated with 170A current (72HV), and it is lowest for specimens fabricated with 150A current weld region (65HV). Microstructure examining at the broken surfaces of tensile specimens, using optical and scanning electron microscopes confirms the experimental findings.

Refinement Properties and Refinement Mechanism of a New Master Alloy Al-5Ti-1B-1RE Refiner

To obtain high-quality grain refiner, a new Al-5Ti-1B-1RE master alloy grain refiner was synthesized by the melt-matching method. Its microstructure and refining effect, refining properties, and refining mechanism were analyzed. The experimental results show that the second-phase particles of Al-5Ti-1B-1RE master alloy are mainly TiB2, Al3Ti, Ti2Al20RE, etc. The magnitude of the free energy ΔG of the synthesis reaction is calculated to be ΔGTiB2 &lt; ΔGAl3Ti &lt; ΔGTi2Al20RE. The nucleation rate N mainly depends on the kinetic atomic diffusion activation energy Q and the thermodynamic nucleation work. The microstructure of commercial pure aluminum refined by the new grain refiner has almost transformed from coarse columnar crystals to fine equiaxed crystals, with an average grain size of 70.2 μm, which was 36.18% and 20.66% smaller than that refined by domestic and imported Al-Ti-B wire master alloy grain refiner, its mechanical properties of tensile strength σb were increased by 11.94% and 8.29%, and elongation δ was improved by 31.79% and 17.41%, respectively. The main refinement mechanism is the formation of TiAl3 on TiB2 particles and the release of RE atoms from the Ti2Al20RE phase, which in turn is partially transformed into the TiAl3 phase, which promotes dual nucleation refinement.

Influence of spinning on the microstructure and mechanical properties of AZ91 alloy tubes

After being subjected to spinning, the evolution of microstructure, texture, mechanical properties of the AZ91 alloy tube during the spinning process was investigated in the present work. The research results indicate that the grains of the AZ91 alloy are significantly refined after spinning. Moreover, a notable grain size difference appears between the inner and outer layers. As the spinning process proceeds, the efficiency of grain refinement in the inner is gradually enhanced, resulting in a reduction in the grain size difference between the inner and outer. The C-axis rotates along RD in the majority of the grains during spinning, resulting in a strong basal texture in the AZ91 alloy tube. Nevertheless, the texture intensity initially increases and then decreases as the spinning process continues. Spinning endows the AZ91 alloy tube with better mechanical properties, the ultimate tensile strength and elongation of which can reach 300 MPa and 13.5 %, respectively, at a spinning deformation of 69 %.

Evolution of microstructure and mechanical properties of warm-rolled W[sbnd]10Re alloy during annealing at 1500 °C

W10Re alloy is preferred for computed tomography anodes with high molar heat capacity. The deformed W10Re alloy will undergo recrystallization and grain growth during service, resulting in reduced mechanical properties, thermal shock resistance, and service life. The aim of this work is to study the microstructure of the warm-rolled W10Re alloy, its evolution of microstructure and mechanical properties after annealing at 1500 °C. During annealing at 1500 °C, recrystallization and growth of the deformed grain occurred with a latent period. The characteristics of deformed grains in the as-rolled alloy and the variation of kernel average misorientation (KAM) and geometrically necessary dislocations (GND) densities during recrystallization are discussed in detail. In high-temperature annealing, lower stored energy can allow the recrystallization behavior to have a latent period, and the residual deformation of the grain can be retained for a long time. In elevated temperatures, the deterioration of the mechanical properties of the alloy is initially evidenced by a notable decline in strength. This is subsequently followed by the loss of plasticity, which occurs as a result of the further degradation of the structure.

Optimization of microstructure and mechanical properties of 7075 aluminum alloy by equal channel angular pressing technology

Abstract The equal channel angular pressing technology, as an effective technique for modifying the surface of a material, has had a significant impact on the microstructure and mechanical properties of the 7075 aluminum alloy. The study achieved the refinement of 7075 aluminum alloy grains and the homogenization of the second phase particle distribution through equal channel angular pressing technology, thereby significantly improving the strength and plasticity of the material. Through orthogonal experimental design, the effects of extrusion angle, extrusion speed, and remelting temperature on material properties were studied. The results showed that appropriate ECAP parameters could effectively regulate the microstructure of 7075 aluminum alloy, thereby optimizing its mechanical properties. Especially in the analysis of equivalent strain rate, when the extrusion angle was 50°, the position of the maximum equivalent strain rate at the forefront point remained unchanged, but the equivalent strain rate decreased to 0.107-1. In the aging hardness analysis, when the number of equal channel angular pressing passes was 3, the aging hardness of G group 7075 aluminum alloy increased to 195HV in the first 5 minutes. The equal channel angular pressing technology can optimize the internal structure of 7075 aluminum alloy and improve the material's plasticity and mechanical properties. The research provides important technical support for the application of 7075 aluminum alloy in high-end equipment manufacturing.

Effect of heat treatment on microstructure and mechanical properties of WE43 alloy fabricated by wire arc additive manufacturing

Heat treatment is an effective method to improve the mechanical properties of Wire Arc Additive Manufacturing (WAAM) WE43 alloy. This study investigates the effects of heat treatment on the microstructure and mechanical properties of the WE43 alloy processed by WAAM. The as-deposited samples exhibit a uniform equiaxed crystal structure, with grain size gradually increasing as the number of deposited layers grows. The as-deposited microstructure comprises eutectics and a small amount of cubic phases, and the phase content escalates as the amount of deposited layers increases, influenced by the cumulative effect of multiple thermal cycles. At lower solid solution temperatures (480 °C × 8 h), most of the eutectic phase remains undissolved. During tensile testing, undissolved eutectics tend to cause stress concentrations, leading to cracks that result in sample fractures, negatively affecting the mechanical properties. At higher solid solution temperatures (520 °C × 8 h), most of the eutectic dissolves, but abnormal grain coarsening (AGC) in the interlayer fine-grain region occurs, causing a significant reduction in the sample's mechanical properties. After solid solution treatment at 500 °C for 8 h, only a small amount of eutectics remains undissolved, and the AGC phenomenon is not observed, resulting in an optimal solid solution effect. Subsequently, after aging treatment at 225 °C for 18 h, dense nanoscale β′′ phases precipitated within the alloy grains, significantly improving the mechanical properties. The samples achieved optimal performance, with UTS, YS, and EL of 323 ± 15.2 MPa, 225 ± 11.3 MPa, and 8.4 ± 1.1 %, respectively.

Laser powder bed fusion of high-strength crack-free Al7075 alloy with the in-situ formation of TiB2/Al3Ti-reinforced phases and nucleation agents

The existence of solidification cracks caused by columnar grains in precipitation-hardened aluminium alloys limit the applicability of Al7075 components manufactured via laser powder bed fusion (LPBF) additive manufacturing. A novel approach was developed to co-incorporate submicron-sized B and micron-grade Ti6Al4V to eliminate hot cracks and to effectively transform coarse columnar grains into fine equiaxed grains, thus improving the mechanical performance of LPBF-fabricated modified Al7075 material. The grain refinement was mainly attributable to the heterogeneous nucleation promoted by the combination of in-situ-formed L12-Al3Ti and TiB2 nano-sized phases. After an optimised T6 heat treatment, excellent comprehensive mechanical properties were achieved, with a tensile strength of 460 MPa and an elongation of 13 %. This research provides an efficient and cost-effective path for addressing crack-sensitive metallic materials used for LPBF additive manufacturing processes.

Improving the mechanical properties and corrosion resistance of a highly alloyed Al-Zn-Mg-Cu alloy through Pre-Treatment at 350°C prior to multi-stage solid solution treatment

This study proposed a new solution treatment process for optimizing the microstructure and properties of Al-Zn-Mg-Cu alloy, by introducing a pre-treatment process that can achieve sufficient recovery and trace recrystallization of the alloy, namely, 350 ° C pre-treatment (PT-350 ° C), prior to traditional solution treatment. Research has found that during the PT-350°C/12h process, a large amount of nanoscale η(Mg(Zn,Cu)2) phases in the extruded state dissolved, diffused, re-precipitated at the larger η(Mg(Zn,Cu)2) phases, and form a large particles, with a size of about 0.74 μm, mainly distributed at the grain boundaries of the matrix. In the subsequent multi-stage solid solution treatment (MST) process, while fully dissolving, they also had a certain inhibitory effect on the growth of matrix grains. More importantly, the alloy underwent sufficient recovery and slight recrystallization during the PT-350°C/12h, significantly reducing dislocation density, suppressing the degree of recrystallization, and refining the alloy grains of the alloy during MST process. The intragranular aging precipitate changed from the η '+ η phase of MST to the GP zone + η' phase of PT-350 °C/12h+MST, with an increase in content and a decrease in size. The distribution of grain boundary precipitates (GBPs) transformed from continuous to discontinuous. The yield strength, ultimate tensile strength, and elongation increased from 740 MPa, 755 MPa, and 2.9% to 778 MPa, 792 MPa, and 5.8%, respectively. The corrosion resistance of the alloy also had significantly improved, in 3.5 wt.%NaCl solution, the corrosion current density decreased from 4.02 × 10-6 A·cm-2 to 8.33 × 10-7 A·cm-2.

Hf atomically modulated grain refinement of FeCrAl alloys

Owing to strong corrosion, radiation resistance and excellent mechanical strength at high temperatures, FeCrAl alloys have attracted much attention in the field of the new generation of nuclear fuel casing materials. The fine and uniform grain organisation further improved the alloy performance. In this study, alloy grain refinement was promoted by adding different Hf contents to FeCrAl alloy. Because of the solute drag effect caused by the segregation of Hf atoms at the grain boundaries and the pinning effect of the highly thermally stable HfC precipitation phase, the grain size of the FeCrAl alloy gradually decreased with increasing Hf content. The dislocation motion process was hindered by HfC, which promoted the formation of dislocation walls and dislocation cells and further evolved into subgrain boundaries; additionally, the increase in the density of the grain boundaries further promoted the segregation of the Hf atoms. Through the coupled proliferation process, Hf atoms effectively promoted the grain refinement of the FeCrAl alloys.

OPTIMIZATION OF HEAT TREATMENT REGIME FOR A NEW BIODEGRADABLE Mg-Zr-Nd ALLOY WITH ENHANCED MECHANICAL PROPERTIES

Purpose. To develop a rational heat treatment regime for a new biodegradable magnesium alloy of the Mg-Zr-Nd system, to ensure enhanced mechanical properties throughout the entire treatment period. Research methods. Differential thermal analysis (DTA) was used to determine phase transformation temperatures. Microstructure analysis was conducted using optical microscopy (“Neophot 32” and “OLYMPUS IX 70”) and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SELMI RЕМ-106I). Mechanical properties were determined using an INSTRON 2801 testing machine. The influence of cooling rate on microstructure and properties was studied using ProCAST simulation software. Heat treatment was carried out in a Bellevue type shaft furnace and a PAP-4M furnace. X-ray analysis was used to detect internal defects in samples. Results. A new heat treatment regime was developed for the biodegradable Mg-3.15Nd-1.25Zr-0.6Zn (wt%) alloy. Using differential thermal analysis and microstructure studies at various quenching temperatures, the optimal quenching temperature was established at 560 °C. Empirical relationships describing the influence of heat treatment parameters on the alloy's microstructure were calculated. The new heat treatment regime (quenching from 560 °C for 8 hours, air cooling + aging at 200 °C for 16 hours) resulted in improved mechanical properties (UTS = 276–282 MPa, δ = 5.2–5.8%) compared to the standard T6 regime. Scientific novelty. For the first time, a comprehensive study of the influence of heat treatment parameters on the structure and properties of a new Mg-3.15Nd-1.25Zr-0.6Zn (wt%) alloy with increased content of alloying elements was conducted. New dependencies describing the influence of quenching temperature on the alloy's grain size were established. Practical value. A new heat treatment regime for the biodegradable magnesium alloy was developed, which ensures complete dissolution of the pseudoeutectic phase and formation of strengthening phases, resulting in improved mechanical properties compared to the standard alloy Mg-2.5Nd-0.4Zn-0.5Zr (wt%) and the standard T6 regime.

Prediction of the thermal-physical properties of amorphous nickel alloys Ni2B, Ni44Nb56, Ni62Nb38 according to component data

The replacement of traditional materials with amorphous alloys and the operation of products made from them are determined by the structural, temporal and temperature stability of disordered environments. In particular, the thermal stability of an amorphous alloy directly depends on its thermophysical characteristics. Therefore, the article demonstrates the applicability of the rule of mixing components and the use of their data on thermophysical properties in the crystalline state to evaluate similar characteristics of alloys from the metal – metalloid and transition metal – transition metal groups in the amorphous phase. It has been established that for the transition metal – transition metal group, the assessment of the heat capacity of amorphous nickel alloys gives a better approximation to the experimentally established values than for an alloy from the metal – metalloid group. The reasons for the discrepancy between the assessment and experimental data for an alloy from the metal – metalloid group are possibly the covalency of the atomic bonds in contrast to the metallic bond for alloys from the transition metal – transition metal group, the smaller size of the metalloid atoms, its greater mobility and the effect on the refinement of alloy grains. The possibility of an amorphous alloy inheriting some properties of one of the components is indicated, which requires experimental verification.
