Summary: The study found that the temperature during impact had almost no effect on the residual compressive strength of damaged sandwich panels, but did affect the damage induced by impact loading. The reduction in strength between pristine panels and those with the least amount of damage tested in the study was more significant than the effect of impact temperature on residual compressive strength.

Summary: The traditional Miura-ori was optimized into Miura-ori with platforms using geometric parameters. Two types of impactors were used to conduct low-velocity impact experiments at specific locations. The study systematically investigated the damage morphology, response characteristics, and failure mechanism under various energy. The results show that the node has better impact resistance than the base due to its crushing absorbing energy. The Miura-ori with platforms sandwich structures show better impact resistance to the flat-ended impactor at the node, while the performance at the base is the opposite.

Summary: The demand for structural materials with high strength, lightweight, corrosion resistance, and environmental resistance has led to the consideration of fiber-reinforced polymer composite (FRPC) materials over traditional materials. Synthetic nanoparticle-reinforced FRPC materials have shown superior performance in various high-end applications. Incorporating nanoparticles, such as montmorillonite nanoclay (MMT) and graphene nanoplatelets (GNP), in carbon fiber-reinforced epoxy composites improves the dynamic mechanical properties, particularly the glass transition temperature. The frequency sweep dynamic mechanical analysis (DMA) test reveals that nanophased FRPCs have a higher storage modulus compared to unmodified samples, indicating their frequency-dependent properties.

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 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: 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.
