Summary: The study focused on the micro hardness and micro structure of Al-Sc alloy and Al-Sc-Zr alloy with different scandium percentages. It was observed that there was only slight difference in hardness during the initial aging stage of the developed alloys, while the Al-Sc-Zr alloy maintained peak hardness for a longer period, showing better thermal stability. Analysis also indicated the inhibition of precipitate growth through precipitation of Zr in the initial aging stage. TEM results revealed the formation of two different sized precipitates in the Al-Sc-Zr alloy after reaching peak hardness.

Summary: The effect of direct aging treatment on the microstructure and strengthening mechanisms of Zr-modified Al-Cu-Mg alloys fabricated by SLM was analyzed in this study. After direct aging treatment, the fine alpha-Al grains were maintained and the S'-Al2CuMg precipitates dissolved.

Summary: The effects of aging treatment on the corrosion resistance of an Al-Cu-Mn-Fe-Zr alloy were investigated. The impedance and polarization resistance increase with aging time and temperature, while corrosion current decreases. Intergranular and pitting corrosion are the main mechanisms, with intergranular corrosion likely in under-aged alloy and pitting corrosion in over-aged alloys.

Summary: In this study, Al-Mg-Sc-Zr-Mn alloy was processed by selective laser melting (SLM) and achieved high relative densities. The research found that the interaction between laser power and scanning speed had the greatest effect on relative densities. The SLM process resulted in the formation of fine equiaxed grains and coarse columnar grains, with a large amount of nano-scale Al-3(Sc,Zr) phases uniformly dispersed in the matrix, which effectively improved the mechanical properties and high temperature stability of the material. After aging treatment, the material's mechanical properties were further enhanced.

Summary: The microstructural evolution and mechanical properties of Al-Mg-Li-Sc-Zr alloys fabricated by ingot metallurgy and gas atomization with hot isostatic pressing were investigated. The HIPed alloy exhibited a fine and uniformly structured microstructure with high strength attributed to grain boundaries, precipitation, and solid-solution strengthening mechanisms. The number fraction of the Al3(Sc, Zr) phase in the HIPed alloy was higher compared to the as-cast alloy, leading to an excellent ultimate tensile strength of 352 MPa.

Summary: The Mg-8Li-4Y-2Er-2Zn-0.6Zr alloy exhibits high damping capacity, tensile strength and elastic modulus after heat treatment and cold rolling processes. The introduction of LPSO phase and formation of twins during cold rolling contribute to the improvement in damping capacity and tensile strength. The high elastic modulus of the cold-rolled alloy can be attributed to the effects of LPSO phase and cold rolling.

Summary: This study investigated the influence of parent austenite grain refinement on the intervariant boundary network in a lath martensitic steel. It found that refining the parent austenite grain led to a decrease in the fraction of certain boundaries in the martensite and an increase in the connectivity of low energy boundaries, ultimately improving the impact toughness.

Summary: Metastable beta Ti alloys based on the Ti-Nb system have attracted attention due to their unique properties. However, the unstable cyclic behavior of these alloys has hindered their widespread industrial use. Recent studies have shown that internal stresses, including those from dislocations, may be responsible for this behavior. This study demonstrates that inter-cycle thermal treatments can mitigate the unstable cyclic behavior, providing a significant breakthrough in our understanding of Ti-Nb superelastic materials.

Summary: This paper systematically investigated the evolution of microstructure in Fe-Ni-Co-Al polycrystalline alloys and its effects on mechanical properties. The results revealed that the migration of grain boundaries in different processes is driven by different factors, which impacts the grain orientation and precipitate formation. In the process of directional recrystallization, grains with specific orientations grow in the grain boundary region and form the dominant orientation, while grains with lower migration rate form the minor orientation. The alloy produced through directional recrystallization exhibited good recoverable strain and superelastic strain, while the alloy produced through solid solution treatment showed no evident superelastic behavior.

Summary: This study employed laser metal deposition to additively manufacture Ti-15Mo wt% alloy, and subsequently subjected it to post-fabrication uniaxial thermomechanical processing. The results showed that different zones in the microstructure remained after processing, and deformation mechanisms mainly involved slip and martensite formation. The compressive mechanical properties were found to be dependent on strain rate, with higher flow stress and compressive strength observed at higher strain rates. Grain structure homogenisation was not achieved, leading to anisotropic tensile properties.

Summary: This research aims to investigate the effect of roughing and finishing reductions on crystallographic texture. The results show significant heterogeneity in the centerline region, with higher intensity of certain textures. Drop Weight Tear Test indicates that steel specimens with lower and medium reductions exhibit superior low-temperature impact toughness compared to steel with higher reductions. The electrochemical hydrogen charging experiments confirm the presence of internal hydrogen cracks only in steel with lower and medium reductions.

Summary: This study examines the effect of Cr additions on the mechanical behavior of TWIP steel at temperatures ranging from 25°C to 350°C. The results indicate that different temperature-dependent strengthening mechanisms, including mechanical twinning, Dynamic Strain Aging, and slip bands, are at play. The stacking fault energy (SFE) influences the percentage of mechanical twinning, which in turn affects the strain hardening rate.

Summary: This study explores the weldability, microstructures, and mechanical properties of two L1(2)-nanoparticle-strengthened medium-entropy alloys after electron beam welding (EBW). The results show that strong yet ductile defect-free joints were produced, with larger grain sizes in the fusion zones compared to the heat-affected zones and base materials. Both EBWed MEAs exhibited high yield strengths, high ultimate tensile strengths, and good fracture strains at 77 K. The V-doping improved the cryogenic mechanical properties of the TMT MEA.

Summary: The mechanical properties and microstructural evolution of C-doped TRIP-assisted HEA under dynamic loading conditions were systematically investigated in this study. The results showed that dynamic tensile deformation led to an increase in yield strength and a decrease in ultimate tensile strength, with a trend towards increased total elongation. The primary deformation mechanisms shifted from TRIP and TWIP effects to deformation twinning and dislocations. The presence of carbides formed through C-doping hindered dislocation slip and promoted the activation of multiple twinning systems.
