Summary: Using synchrotron X-ray nano-computed tomography and finite element analysis, we reconstructed the nanostructure of shear bands (SBs) and investigated their formation and evolution in a bent heterogeneous Pd-based metallic glass fiber. We found that in addition to plain SBs (PSBs), there were hidden SBs (HSBs) with density fluctuations inside the metallic glass. The HSBs had average densities 5%-25% smaller than the surrounding matrix and thicknesses ranging from 100 nm to 530 nm. The structures of the HSBs were closely related to the heterogeneous structure and local strain rate of the metallic glass.

Summary: Dynamic mechanical relaxation is an important metric for studying viscoelastic amorphous solids. The relaxation behavior of amorphous solids, due to their heterogeneous microstructure, often deviates from the Debye relaxation. The distribution of relaxation time based on the stretched exponential function or power law is commonly used to describe non-Debye relaxation, but its applicability to real amorphous materials is still under discussion.

Summary: In this study, we developed a series of medium-entropy alloys (MEAs) with high strength, superior fracture toughness, and ultra-high corrosion resistance. Interestingly, our MEAs exhibit an unusual anti-corrosion behavior as their corrosion resistance increases with increasing acidity. This behavior can be attributed to the surface chemical complexity of our MEAs, which facilitates the formation of metastable medium entropy passive films.

Summary: Since 2004, the design of high entropy alloys (HEAs) has sparked significant interest in the materials science community due to their exceptional structural and functional properties. By incorporating multiple principal elements into a common lattice, a highly distorted lattice can be created, enabling HEAs to offer a promising combination of mechanical and physical properties that are not typically observed in conventional alloys. This article provides an extensive overview of multifunctional HEAs with severe lattice distortion, including theoretical models, experimental and computational methods, and the impact of lattice distortion on their mechanical, physical, and electrochemical properties. The review aims to stimulate further research into the study of distorted lattices in crystalline solids.

Summary: Mechanical cycling is an effective method to improve the mechanical properties of metallic glasses. This study investigates the anelastic origin of rejuvenation by mechanical cycling in La30Ce30Ni10Al20Co10 metallic glass using DSC and DMA. The results show that mechanical cycling activates flow defects, leading to anelastic strains and energy storage, which can be observed as larger relaxation enthalpy on DSC curves. However, the excess relaxation enthalpy caused by anelastic strain is released over time, suppressing atomic mobility and increasing β relaxation activation energies. The strategy of mechanical cycling at small strains expands the energy states of metallic glasses.

Summary: The stress relaxation dynamics of La60Ni15Al25 metallic glass in ribbon and bulk samples were studied. It was observed that the stress decay of deep glass is mediated by beta relaxation, which contributes about 5% to the total stress. The characteristic time of stress relaxation near the glass transition coincides with that of alpha relaxation, suggesting a direct relationship between the two relaxation processes. A possible atomic mechanism involving both relaxation and deformation is proposed based on the evolution of shear transition zone. The findings provide a strategy to detect beta relaxation associated phenomena and clarify the roles of relaxation modes in the nonelastic deformation of amorphous matters.

The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
