Summary: The properties of high entropy alloys depend on their phase structures and compositions. A green approach using molten salt electrolysis was developed to efficiently prepare homogeneous powdery phase FCC Fe0.5CoNiCuZnx HEAs containing highly volatile elements such as Zn. The electrocatalytic activity of the HEAs towards oxygen evolution reactions was found to be optimized by the addition of Zn, with the HEA(Zn-0.8) exhibiting the best OER activity and stability.

Summary: Amorphous high-entropy alloys exhibit optimized bonding energy and enhanced intrinsic catalytic activity compared to crystalline ones, with even better performance after electrochemical etching treatment. The nanostructured amorphous Fe29Co27Ni23Si9B12 HEA ribbon, fabricated through a melt spinning method combined with electrochemical corrosion etching process, shows superior electrocatalysis activity, requiring lower overpotential and higher current density. Density functional theory calculations suggest that the amorphous structure weakens the interaction between the alloy surface and intermediates, resulting in optimized adsorption Gibbs free energy.

Summary: This study reports a novel Pt single-atom catalyst for highly efficient electrochemical catalysis and sensing of glucose. The loading of Pt single atoms increases with Co doping, providing more anchoring sites for Pt SAs. The resulting Pt-1/Ni(6)Co(1)LDHs/NG exhibits low oxidative potential, high sensitivity, excellent selectivity, and great stability. The boosted performance of Pt-1/Ni(6)Co(1)LDHs/NG originates from its stronger binding energy with glucose and the synergistic effect of Pt SAs, Co doping, and NG.

Summary: The research on liquid-liquid transition (LLT) has greatly enhanced the understanding of the liquid structure and evolution, with significant implications for glass formation. However, the impact of LLT on vitrification and glass structures is still unclear due to experimental challenges in exploring LLT in high-temperature melts. This study examines LLT in Zr-Cu-Ni-Al melts and reveals that superheated fragility is closely related to glass-forming ability. The competition between crystal-like and icosahedral-like clusters affects the crystallization behavior and changes in both medium-range order structure and short-range order structure indicate LLT.

Summary: The structural evolution near the crystalline/matrix interface in CuZr-based metallic glass composite (MGC) was investigated using in situ transmission electron microscope (TEM) tensile straining and molecular dynamics (MD) simulation. Plastic deformation of the crystalline phase occurred before the amorphous phase, involving recoverable martensite transformation, dislocation accumulation at the interface, and local amorphization between grains. Fracture did not occur along the interphase interface, but within the crystalline phase near the interface, indicating a strong interface and high work hardening rate of the crystalline phase. MD simulations revealed that the amorphous phase was marginally metastable compared to the stable B2 phase, while the B19' martensitic phase was metastable with higher energy, explaining the easy mutual transformation between B2 and amorphous phase, and the less frequent transformation product of B19' phase from B2 during straining.

Summary: In metallic glass composites (MGCs), the presence of crystalline phases leads to structural heterogeneity in the amorphous matrix near the crystalline phase, resulting in differences in mechanical properties at the micro- or nano-scale near the crystalline/matrix interface. This study quantitatively relates the pile-up height to the activation volume of shear transformation zones (STZs) to characterize this difference using nanoindentation technology. Molecular dynamics simulations were conducted to investigate the activation behaviors of STZs during the nanoindentation process of the amorphous matrix, and the influences of crystalline phases on the deformation behaviors of the amorphous matrix near the interface in MGCs were analyzed in detail.

Summary: Amorphous alloy composites (AACs) with reinforcing crystalline phases exhibit superior mechanical properties compared to their base amorphous alloy counterparts. A study on Cu-Zr based AACs reveals that the B2 phase particles embedded in the amorphous matrix are actually heterogeneous at the sub-micron scale, and the amorphous phase exhibits a gradient in free volume content towards the interface. This research provides valuable insights into the crystallization mechanism of the iso-stoichiometric B2 phase in Cu-Zr based AACs.

Summary: The structure features of Cu62Zr34.4Al3Nb0.6 amorphous alloy composites (AACs) were studied using experimental characterization and first-principles calculation. Element segregation, a common phenomenon in conventional alloy materials, does not occur in the two phases (crystalline and amorphous) of AACs due to complex solid solution. By calculating different structural models, including interstitial solid solution, substitutional solid solution, B2, and amorphous phase, the lattice parameters, electron distribution, charge transfer, and electrical potential, which are directly related to atomic bonding and lattice parameters, were obtained. Finally, the formation and stability of solid solution in the crystalline and amorphous phases were elucidated using first-principles calculation. This work has important guiding significance for understanding the two-phase structure and solidification mechanism in AACs materials.

Summary: Laser-shock peening (LSP) is widely used to improve the mechanical properties of metallic components. In this study, the structure and nano-mechanical behaviors of a Ti40Zr25Ni3Cu12Be20 bulk metallic glass (BMG) before and after LSP processing were investigated. The LSP-treated BMG sample remains amorphous, and there is a reduction in local order extent with increasing laser-beam energy, leading to an increase in free-volume contents. The higher free-volume content results in a greater shear-band density and lower nano-hardness in the studied BMG samples.
