Summary: In cyclic tensile creep experiments at a constant temperature, strain deformation in metallic glasses accelerates structural relaxation by causing the shrinkage and annihilation of flow units. This has a significant negative impact on the beta-relaxation behavior and relaxation enthalpy, leading to an aging phenomenon, indicating a close correlation with the inhomogeneous microstructure and potential defects of flow units.

Summary: The corrosion behavior of Zr56Cu24Al9Ni7Ti4-xAgx (x = 0, 1, 2, 3, and 4) bulk metallic glasses in acid-base-salt solutions was systematically studied using electrochemical methods. The results demonstrated the excellent corrosion resistance of the alloys. It was further confirmed that the replacement of a small amount of Ti with Ag effectively improved the corrosion behavior of the alloys. Different morphologies, including honeycomb-like corrosion pits, dark spots, and dents, were observed on the surface after polarization in different solutions.

Summary: The effect of adding N on the thermodynamics and corrosion resistance of as-cast Zr55Cu30Ni5Al10 bulk metallic glass (BMG) was investigated. Nitrogen-doped BMG was found to have easier nucleation but more difficult nucleation growth compared to non-doped BMG. Nitrogen doping increased the corrosion potential slightly, but decreased the corrosion current density by about three orders of magnitude. Nitrogen also improved the oxide film resistance, weakened the surface corrosion diffusion effect, and enhanced the corrosion resistance of Zr-based BMGs.

Summary: The study revealed the hierarchical structure of BMGs through nanobeam electron diffraction experiments, showing that the local hardness of microscale domains decreases with the size and volume fraction of atomic clusters with higher local MRO. A model of ductile phase softening was proposed to enable the design of BMGs in the future by tuning the MRO size and distribution in the nanostructure.

Summary: The correlation between atomic-scale structure and glass-forming ability of ternary bulk metallic glasses was investigated using molecular dynamics simulation. It was found that the potential energy of the icosahedra reflects the geometric ordering, while the virial stress energy density reveals the chemical ordering. Based on this discovery, a new prediction criterion for glass-forming ability was proposed and validated using experimental data.

Summary: Laser shock peening (LSP) treatment significantly affects the phase structure and properties of titanium-based BMG materials, promoting rejuvenation and introducing heterogeneity. This leads to improved plasticity and resistance to crack propagation. LSP-1 specimen exhibits higher hardness and plasticity, reducing fatigue peeling wear caused by brittleness. However, excessive LSP results in increased susceptibility to pitting and significantly reduces tribocorrosion resistance.

Summary: The amount of globally recycled e-waste is less than 20% of the total produced. One of the causes for this low recycling rate is the complex and expensive selective sorting of metals. However, recent research has shown that high entropy alloys (HEAs) can be made from complex alloy mixtures, reducing the dependence on pure critical metals. It has been demonstrated that e-waste can be used to produce competitive HEAs.

Summary: In this study, a novel medium-entropy alloy (MEA) (Fe65Ni15Cr10Co10)92Ti5Al3 with a dual heterogeneous structure was developed by adding Ti and Al to a previously reported Fe65Ni15Co10Cr10 MEA. The MEA exhibited ultra-high ultimate tensile strength and work hardening extent at room temperature. The addition of Ti and Al induced precipitation and resulted in a continuous FCC -> BCC martensitic transformation and a transformation-induced plasticity effect. The excellent mechanical properties of the alloy were attributed to the synergistic effects of hetero-deformation induced strengthening, precipitation strengthening, and TRIP.

Summary: This study focuses on the influence of the thermomechanical protocol on the aging or rejuvenation of glass by decoupling the thermal and mechanical processes. The results show that Labased metallic glass exhibits material hypomnesia, with a clearer rejuvenation trend observed after imposing increasing amplitude strain oscillations. There is a threshold value of the oscillation amplitude that separates the effects of the protocol into acceleration of aging or rejuvenation. This study reveals the correlation between the thermomechanical properties of metallic glass and the previous application of strain oscillations of various amplitudes, providing an effective tool for regulating the structural state of metallic glasses through a simple-operated method.

Summary: We report the formation of large and highly twinned dendrites of the Al13Fe4 approximant phase embedded in an fcc Al-rich matrix. Using a rapid cooling technique, the approximant appears as a 10-fold dendrite. The grain distributions within the arm are complex and a single dendrite arm can contain up to four different orientations. Three types of twins, namely {100}, {001} and {201} twins, have been identified. A growth mechanism involving heteroepitaxial growth from a decagonal Al-Fe quasicrystalline seed is proposed to explain the formation of these specific 10-fold motifs.

Summary: The homogeneous superelastic behavior in shape memory alloys (SMAs) is crucial for their functional and structural fatigue properties, as well as their stable elastocaloric effect (eCE). In this study, a Ti-22Nb-4Zr-2Ta plate was prepared with a strong recrystallized texture, resulting in a completely recoverable superelastic strain and narrow hysteresis. The observation of strain and temperature evolution revealed the importance of diffuse transformation and favorable texture in achieving mesoscopically homogeneous transformation and related elastocaloric effect.

Summary: This study investigates the effect of Cu and Al addition on an alloy containing multiple principal elements. The results show that adding small amounts of Cu can improve the alloy's ductility and the hardness of the FCC phase can be predicted using a hybrid model. Unlike previous studies, the corrosion resistance of the alloy is not affected by Cu addition, indicating its potential for further development into a fine-grained stainless steel alloy.
