Summary: Greater advantages of employing hybrid reinforced advanced aluminum matrix composites have been highlighted recently. In this study, Al6082 bimodal hybrid composites embedded with different proportions of SiC and TiO2 particles were fabricated using a modified stir-squeeze cast technique. Microstructural analysis revealed that the properties of the composites deteriorated when the content of SiC exceeded 3 wt.%. The incorporation of 3 wt.% SiC and 0.5 wt.% TiO2 resulted in the maximum enhancement of mechanical properties in Al6082 alloy.

Summary: In this study, graphite is used as the reinforced phase in aluminum metal matrix nanocomposites (AMMNCs) due to its high strength and lubricating properties. The AMMNCs are processed using ultrasonic-stir-squeeze casting process to ensure homogeneity and minimize porosity. Characterization techniques like x-ray diffraction and scanning electron microscopy are used to investigate the phase and microstructure. AMMNCs show lower density and improved hardness compared to as-cast aluminum alloy (AA2014). The addition of graphite enhances the wear properties of AMMNCs, but the wear rate is affected by factors such as graphite concentration and applied load. Post-tribological characterization provides detailed information on the influence of hardness and elastic modulus on the tribological properties of AMMNCs.

Summary: This study compares the mechanical behavior and microstructural characteristics of Cu matrix hybrid composites reinforced with SiC-Gr(p) and WC-Gr(p) fabricated through the stir casting process. The dispersion of reinforced particles in the composites was uniform, and the presence of SiC, WC, and Cu alloy was confirmed by XRD. The addition of hard ceramic materials improved the tensile behavior and microhardness of the Cu-based MMCs, with the WC-Gr reinforced composites exhibiting superior mechanical properties compared to the SiC-Gr reinforced composites. The fracture surfaces indicated ductile fracture in both hybrid composites.

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.
