Summary: The evolution of long plate-shaped S' phase in the spray-formed fine-grained Al-Cu-Mg alloy during aging after rapid cold punching deformation was studied using TEM, XRD, and hardness test. Results showed that the S' phase undergoes distortion, brittle failure, and redissolution during deformation, leading to the transformation of its morphology and increased hardness after aging.

Summary: The evolution mechanism of the second phase in the homogenization process of Al-Zn-Mg-Cu aluminum alloy was thoroughly investigated. The results revealed that the phase transition of Mg(Zn, Cu, Al)2 to S(Al2CuMg) occurs due to the interdiffusion between Zn and Al atoms at the interface during homogenization at 420 degrees C for 15 to 30 min. Additionally, the dissolution of S(Al2CuMg) into the Al-matrix is governed by the interdiffusion of (Mg, Cu atoms) and Al atoms. Notably, the 0(Al2Cu) phase plays a crucial role as an intermediate transition phase facilitating the dissolution of S(Al2CuMg) into the Al-matrix.

Summary: A new X-ray approach was used to quantify second-phase precipitates in friction-stir welded 2519-T820 aluminum alloy. The stir zone material was found to contain a significant fraction of non-equilibrium theta' and theta '' phases. Based on this result, it was concluded that the widely accepted concept of FSW-induced precipitation phenomena is oversimplified and requires revision.

Summary: This study investigated the mechanical properties and constitutive relationship of 6008-T6 aluminum alloy under dynamic impact loading through dynamic impact and microscopic experiments. The results showed strain hardening effects in the alloy, with refined grains, increased dislocation density, and more second-phase particles (mainly Mg2Si) as the loading strain rates increased. The interaction of dislocations and precipitation of second-phase particles improved the material's strength and increased its flow stress. A constitutive model for dynamic impacts was developed based on dislocation density evolution and the reinforcing effects of second-phase particles. Additionally, a damage evolution equation for 6008-T6 aluminum alloy was obtained by introducing the energy release rate. The study provides a theoretical basis and analytical tool for structural design and safety evaluation of high-speed trains.

Summary: Two generations of garnet are identified in a granite and a pegmatite in the Gangdese orogen, with the first generation representing an early nucleation stage related to magmatic-hydrothermal fluids, and the second generation crystallizing in the presence of granitic magma in the pegmatite. The granite garnets display homogeneous characteristics typical of magmatic garnets, while the pegmatite garnet's composition suggests crystallization from the same granitic magma.

Summary: This study investigated the role and mechanism of VPS72 in hepatocellular carcinoma progression. It was found that VPS72 was highly expressed in hepatocellular carcinoma tissues and cell lines and was associated with poor prognosis. Knockdown of VPS72 inhibited cell proliferation, invasion, and migration. VPS72 was shown to bind to KAT5, and overexpression of KAT5 reversed the suppressive effects of VPS72 knockdown. Additionally, VPS72 silencing downregulated p-PI3K and p-AKT expression, which was restored by KAT5 overexpression. Overall, these findings suggest that VPS72 binding to KAT5 promotes hepatocellular carcinoma progression through the regulation of the PI3K/AKT signaling pathway.

Summary: To obtain a strong Goss texture in Al-Cu-Mg alloy sheet, texture evolution and related mechanisms during solution treatment were studied. It was found that the Goss texture can further develop during solution treatment, which is attributed to the growth of recrystallized Goss grains into deformed Brass grains and the slow growth of recrystallized Goss grains into substructured random grains. The effect of particles stimulated nucleation (PSN) on Goss texture formation and development was also revealed, showing that large Fe-rich phases restrict Goss grain nucleation and growth while relatively small θ and S phases do not hinder the development of Goss texture.

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: 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.
