Summary: In this study, a Si/Cu composite interface model with different IMC layer thicknesses was established using molecular dynamics simulation. The Si/Cu interface was found to fail in a quasi-brittle fracture mode, with crack propagation along the Si/IMC interface. IMC was shown to increase the critical strain energy release rate, while the equivalent modulus did not increase monotonically.

Summary: This study investigated the use of graphene nanosheets (GNSs) at different mass fractions to enhance the performance of Sn/Cu solder joint. Results showed that 0.05% GNSs addition effectively promoted the spreading area of the composite solder while inhibiting the growth of intermetallic compound (IMC) layer. Additionally, GNSs doping improved the mechanical properties of the solder joint, transforming the fracture pattern from brittle to ductile.

Summary: In this study, the impact of phase conditions on the tensile behaviors of Ti-Cu alloys was investigated. The results showed that the mechanical properties of the alloys were strongly influenced by the Cu content in alpha lath, which depended on the volume of Ti2Cu. A higher volume of Ti2Cu resulted in lower Cu content in alpha lath, leading to higher elongation and lower strength. Additionally, Ti2Cu exhibited superior antibacterial properties compared to Cu-supersaturated alpha lath. This study provides new insights for the design of Ti-Cu alloys as biomaterials.

Summary: Magnesium (Mg) metals, as a promising lightweight structural material, have been widely used but are limited by their low corrosion resistance and poor mechanical properties. Laser surface treatment is a common approach to improve the mechanical strength and corrosion resistance of Mg metals. This article briefly describes the changes in surface organization and the creation of new structures through laser treatment on Mg surfaces, and reviews the effects on wettability, hardness, friction wear, degradation, biocompatibility, and mechanical properties. The limitations and development trends of laser treatment on Mg metals research are also discussed.

Summary: This study investigates the effect of annealing time and temperature on Al5052/Cu multilayer composites processed by accumulative roll bonding (ARB). Results show that different annealing conditions lead to variations in the interfacial and mechanical properties of the composites, with the maximum tensile strength of 345 MPa achieved at 400 degrees C for 90 min. OM and SEM analyses reveal different fracture surfaces and macroscopic paths under different annealing conditions.

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.
