Summary: New high-entropy metallic glasses were produced by adding B and Si to the Fe25Co25Cr25Ni25 high entropy alloy, resulting in extremely hard materials through structural relaxation and nanocrystallization. The study explored the effects of composition and annealing treatments on structure and mechanical properties, finding that the relative amount of B and Si determines the main nanocrystalline phase and influences mechanical behavior.

Summary: The effect of yttrium (Y) on the glass-forming ability (GFA), mechanical properties and corrosion of (Cu50Z-r43Al7)100-xYx alloys was studied. The addition of Y improved the GFA of Cu50Zr43Al7 alloy, with a GFA of 15 mm obtained for (Cu50Zr43Al7)98Y2. The bulk metallic glasses (BMGs) exhibited limited plastic strain but achieved high compressive fracture strength and Young's modulus. The corrosion resistance of the BMGs was improved by the addition of Y.

Summary: The dynamic mechanical relaxation processes of metallic glasses were investigated in this study. The results showed that alpha relaxation was observed in the HE-MGs and Vit1 MG. The activation energies of the HE-MGs were higher than that of the Vit1 MG. The dynamic mechanical properties were discussed in light of the KWW and QPD models, indicating different dynamic heterogeneities and defect concentrations in the four MGs.

Summary: A family of novel Os-Co-Ta-B high-temperature bulk metallic glasses (HTBMGs) with high glass transition temperature, Vickers microhardness, and compressive strength was fabricated by introducing high-modulus refractory metal Os and strong-covalent metalloid B. The impressive strength is attributed to the strong bond characteristics especially for Ta-Os and B-B bonds. The castable OsCo-based HTBMGs with superior mechanical properties and high thermal stabilities are significant for high-temperature applications as advanced structural materials.

Summary: Developing materials with excellent properties has always been a relentless pursuit of mankind. Metallic glasses (MGs) could be the ideal metallic materials if their size could be scaled up to be comparable to traditional metals. Various methods have been attempted to address this challenge, including thermodynamics-based alloy, 3D printing, and the recent artificial intelligence-guided optimal alloy. In this study, a simple and flexible approach was demonstrated to manufacture giant MGs (GMGs) with diameters more than 100 mm through the thermo-joining process. The jointed GMG samples exhibit almost the same performance as the as-cast ones, and the ability to manufacture complex 3D components such as the Chinese Zodiacs was also demonstrated. This approach may overcome the longstanding problem of glass forming ability (GFA) limitations in alloy systems and pave the way for fabricating size unlimited MGs.

Summary: The newly discovered color-changing metallic glasses can continuously and spontaneously change color under ambient conditions, mainly created by light interference and optical bandgap energy of the oxide layer. The unique qualities of these glasses, including continuous oxidation, uniform oxide layer thickness, and fast color-changing capabilities, are connected to the oxygen affinity of cerium, the glassy structure, and the yttrium dopant regulation. This work not only introduces a new direction for metal oxidation, but also highlights new applications for metallic glass.

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 study found that non-inert casting atmospheres can significantly improve the glass forming ability of P-containing Fe-based BMGs, while not affecting their thermal and magnetic properties. The surface composition of the BMGs varied greatly with different casting atmospheres, while the bulk composition remained unchanged. The enhancement of GFA by non-inert casting atmospheres was mainly attributed to the increased surface tension resulting from the elimination of oxygen element and the alloying effect of nitrogen element in the casting atmospheres.
