“…36 The Zr 3p spectrum exhibits two peaks assigned as Zr 3p 3/2 and Zr 3p 1/2 which have peaks at 333.38 and 346.87 eV. As observed by Nie et al, 37 a weak Zr 3s peak was detected at 432.19 eV which is not due to metallic Zr but due to oxidized Zr from the surface. Peaks at 934.13 eV and 954.80 eV are observed on the Cu 2p spectrum region (Fig.…”

“…When the temperature increases to 300 °C, the preexisting mixed oxides are entirely covered by the newly generated tetragonal crystalline ZrO 2 . Nie et al [27] also revealed the similar covering procedure of oxide, and a ZrO 2 -enriched oxide layer with film thickness of 150-260 nm was detected. Meanwhile, tetragonal crystalline CuZr 2 phase exists simultaneously.…”

Novel crystallization behaviors of Zr 55 Cu 30 Al 10 Ni 5 bulk metallic glass are investigated. On the one hand, mixed oxides, including CuO, CuAlO 2 , CuAl 2 O 4 and ZrO 2 , show sequential oxidation process determined by coupling effects of specific cyclic load and temperature. On the other hand, at a temperature (100 °C) by far lower than T g of 412 °C, under cyclic loading condition, non-oxidized binary alloy CuZr 2 is precipitated; the thermo-mechanical coupled effects of temperature below T g and fatigue accumulation on the non-oxidized crystallization behaviors are revealed. Meanwhile, at a constant temperature of 400 °C, by comparing among the XRD patterns, respectively, obtained from tensile, creep and fatigue fractures, the dominating effect of cyclic load on the generation of non-oxidized CuZr 2 is verified. Furthermore, the crystallization behavior of amorphous phases under cyclic loading condition is observed through TEM micrograph and diffraction pattern at 100 °C.

“…[ 75,76 ] How oxide scales influence corrosion resistance strongly depends on the chemical composition and structure of the oxide films formed during oxidation. [ 77 ] Native oxide films, which are amorphous and homogeneous, do not exhibit any weak points such as grain boundaries, lattice defects, cracks, or dislocations and, thus, exhibit strong corrosion resistance. [ 78 ] Native oxide films grown on Zr 59 Ti 3 Cu 20 Al 10 Ni 8 metallic glass remarkably enhanced the glass corrosion resistance and passivity, mainly by eliminating surface Cu enrichment.…”

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.
