“…Then corrosion is stopped after the crystalline phases dissolves and a continuous glass matrix is exposed to solution. If the crystalline phase is nanoparticle and presents high chemical potential, the corrosion resistance of metallic glass composite will not reduce, even increase for some metallic glass alloy [39,42].…”

Metallic glasses exhibit excellent corrosion resistance and electrocatalytic properties, and present extensive potential applications as anticorrosion, antiwearing, and catalysis materials in many industries. The effects of minor alloying element, microstructure, and service environment on the corrosion resistance, pitting corrosion, and electrocatalytic efficiency of metallic glasses are reviewed. Some scarcities in corrosion behaviors, pitting mechanism, and eletrocatalytic reactive activity for hydrogen are discussed. It is hoped that the overview is beneficial for some researcher paying attention to metallic glasses.

“…[ 20 ] Because ionic diffusion is a thermally activated process, oxidation rates increase with increasing temperature. [ 21 ] Zhang et al. reported that in contrast to most metallic glasses, a Ti–Zr–Hf–Cu–Ni–Be high‐entropy metallic glass exhibited decreased mass gain during prolonged oxidation after the early increased mass gain stage, implying that initially formed oxides are unstable.…”

[21] Zhang et al reported that in contrast to most metallic glasses, a Ti-Zr-Hf-Cu-Ni-Be high-entropy metallic glass exhibited decreased mass gain during prolonged oxidation after the early increased mass gain stage, implying that initially formed oxides are unstable. [22] Moreover, the very early Cu 64 Zr 36 metallic glass oxidation stage, within nanoseconds and cannot be experimentally observed, obeys the inverse logarithmic law according to molecular dynamics simulations, suggesting that ionic drift through the oxide controls oxidation in response to electric fields.…”

Owing to their unique structure and outstanding properties, metallic glasses are a novel class of structural and functional materials with vast application prospects. However, the metastable amorphous structures and chemical activity of metallic glass constituent elements lead to frequent oxidation during preparation, processing, and application. Comprehensively understanding the oxidation behaviors and underlying mechanisms of metallic glasses is essential for gaining knowledge of metallic glass structures and properties and for promoting engineering applications. Although many studies have examined these issues, more investigations are still required to explore potential industrial applications of metallic glasses. Here, recent research on metallic glass oxidation is consolidated by summarizing the oxidation influence on metallic glass structure, performance, and application and the possibilities and feasibility of oxidizing metallic glasses to reinforce materials or develop material systems are discussed.

“…Alloying is an effective method to improve the GFAs of BMGs. Currently, numerous Ti-based BMGs have been developed, including Ti-(Cu, Be) systems [17,18], Ti-Cu-(Ni, Co,) systems [19,20], Ti-Zr-(Cu, Be) systems [17,21], Ti-Zr-Cu-Ni-Be systems [22], and the like. Typical ternary Ti-Zr-Be BMGs with good GFAs can reach the critical diameter of 5 mm [23].…”

A series of Ti41Zr25Be34-xNix (x = 4, 6, 8, 10 at.%) and Ti41Zr25Be34-xCux (x = 4, 6, 8 at.%) bulk metallic glasses were investigated to examine the influence of Ni and Cu content on the viscosity, thermoplastic formability, and nanoindentation of Ti-based bulk metallic glasses. The results demonstrate that Ti41Zr25Be30Ni4 and Ti41Zr25Be26Cu8 amorphous alloys have superior thermoplastic formability among the Ti41Zr25Be34-xNix and Ti41Zr25Be34-xCux amorphous alloys due to their low viscosity in the supercooled liquid region and wider supercooled liquid region. The hardness and modulus exhibit obvious variations with increasing Ni and Cu content in Ti-based bulk metallic glasses, which can be attributed to alterations in atomic density. Optimal amounts of Ni and Cu in Ti-based bulk metallic glasses enhance thermoplastic formability and mechanical properties. The influence of Ni and Cu content on the hardness of Ti-based bulk metallic glasses is discussed from the perspective of the mean atomic distance.
