Summary: Dynamic mechanical analysis was performed on two metallic glasses with distinct beta relaxation features. The presence of free-volume zones and inelastic deformation behavior led to significant mechanical hysteresis loops in dynamic cyclic loadings, which can be described using a viscoelastic model. Annealing below the glass transition temperature reduced the concentration of free-volume zones, providing insights into improving the mechanical properties of high entropy metallic glasses.

Summary: In this study, the microstructure, thermal stability, and anti-corrosion properties of quinary Al-Ni-Y-Co-Si high-entropy metallic glass ribbons were investigated. The results showed that the wheel speed had little influence on the thermal stability of the ribbons. Increasing the wheel speed resulted in a decrease in Vickers microhardness of the ribbons. The alloy ribbons fabricated with a wheel speed of 2000 rpm exhibited the lowest corrosion rate and the best corrosion resistance.

Summary: In this study, the magnetic behavior and magnetocaloric effect of high-entropy and medium-entropy bulk metallic glasses (BMGs) were systematically investigated. The results showed spin glass-like behavior and large magnetocaloric effect at cryogenic temperatures in all BMGs. The influence of configuration entropy on magnetic response and magnetocaloric effect was discussed. It was found that configuration entropy could alter magnetic phase transition temperature, magnetic hysteresis, and refrigeration capacity in these BMGs. However, increasing configuration entropy did not lead to distinct differences in magnetic entropy change. The BMGs in this study exhibited good glass-forming ability and promising magnetocaloric effect, making them potential candidates for cryogenic refrigerants.

Summary: High-entropy metallic glasses (HE-MGs) are a new class of materials with unique properties. However, the understanding of composition-structure-property relationships is limited. We propose a framework + fluctuation model based on the Bethe-Slater (BS) curve, which explains the effect of the short-range distribution of metal elements on the magnetism of HE-MGs. The model is further confirmed by ab initio molecular dynamics simulations and provides insights into the development of high-performance HE-MGs.

Summary: The calorimetric and dynamical glass transitions are decoupled in high entropy metallic glasses (HEMGs), and the underlying mechanism and connection to atomic structure are not understood. Molecular dynamic simulations are performed to investigate the glass transition behavior of different HEMG model systems. It is found that the effect of mismatch entropy plays a critical role in decoupling vitrification kinetics/α-relaxation in HEMGs, and the atomic size difference contributes significantly to the sluggish diffusion and decreased dynamic heterogeneities.

Summary: By combining the advantages of refractory high-entropy alloys (RHEAs) and rare-earth tantalate, the study investigated the effect of Y0.5Gd0.5TaO4 on the microstructures, mechanical properties, and thermophysical properties of NbMoTaW. The addition of rare-earth tantalate resulted in stable microstructures. With an increasing content of Y0.5Gd0.5TaO4, the hardness gradually increased while the compressive strength and fracture strain decreased. The addition of Y0.5Gd0.5TaO4 effectively increased the thermal diffusivity but had minimal impact on the linear thermal expansivity. This study fills the gap in understanding the effect of rare-earth tantalate on the microstructures, mechanical properties, and thermophysical properties of RHEAs, and provides helpful guidance for RHEAs design.

Summary: The present study has designed and prepared a novel Zr22.5Ti22.5Hf22.5Ni22.5Ta10 high-entropy amorphous alloy with excellent thermal stability and corrosion resistance. The hysteresis diffusion effect caused by the high mixing entropy of the multi-principal system affects the formation of the crystalline phase and improves thermal stability. The alloy exhibits excellent corrosion resistance compared to 316 L in 3.5 wt% NaCl solution. The XPS results indicate that the passive film of Zr22.5Ti22.5Hf22.5Ni22.5Ta10 is rich in oxides of Zr, Ti, Hf, and Ta, which provides excellent resistance to chloride ion attack.

Summary: By utilizing facet engineering, a Au/Cu heterostructure with Au(110)/Cu(110) was constructed, exhibiting the highest yield rate towards multicarbon alcohols. Electrochemical analysis revealed that the enhanced activity resulted from high-conversion capabilities of both CO2-to-CO and *CO-to-C2+ alcohols. It was also confirmed that the buildup of *CO was more crucial than the atomic arrangement of Cu surface for multicarbon production.

Summary: Three kinds of Al-based amorphous coatings with high amorphous content (89, 86 and 87%) and low porosity (0.34, 0.43 and 0.35%) were prepared by low-temperature high-velocity oxygen-fuel (LT-HVOF). The coatings had higher hardness values (320, 410 and 330 HV0.1) than 45 steel and general aluminum alloys. Among them, the AlNiCoYLa coating had the highest hardness, about 7 times that of the traditional Al coating. The corrosion resistance of the coatings in 3.5 wt.% NaCl solution was arranged as: AlNiCoY coating > AlNiCoYLa coating > AlNiCoYLaGd coating. The corrosion resistance of the coatings was much higher than that of 45 steel and similar to that of 2024 aluminum alloy.

Summary: In this study, the microstructural evolution and mechanical properties of Al0.25CrFeNi1.75Cux (x = 0-0.7) high entropy alloys were investigated. The microstructural analysis showed that high Cu doping changed the microstructure of the alloys, transitioning from a single FCC phase to a structure with FCC matrix and AlCu-type phase characteristics. The alloys exhibited dendritic morphology, with the average size of dendrites and secondary dendrite arm spacing significantly decreasing at high Cu content. Tensile tests revealed that increasing Cu concentration from 0 to 0.7 led to a 35.4% increase in yield strength and a 12.1% increase in ultimate tensile strength, but a decrease in elongation by 47.2%. These enhancements in mechanical properties were attributed to fine grain strengthening, second-phase hardening from AlCu-rich precipitation, and solid-solution strengthening.

Summary: The study investigates the role of gut microbiota in regulating aging-related processes under high-density crowding stress. High housing density increases stress hormone levels, accelerates aging processes, and reduces lifespan in Brandt's voles. Fecal microbiota transplantation and butyric acid administration have similar effects on aging-related markers. Gut microorganisms may play a significant role in regulating density-dependent aging and can be potential targets for alleviating stress-related aging in humans.
