Influence of Oxidation on Structure, Performance, and Application of Metallic Glasses

Abstract

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.

Amorphous Cu–W Alloys as Stable and Efficient Electrocatalysts for Hydrogen Evolution

“…Amorphous alloys are a kind of material with long-range disordered atomic arrangement. In contrast to their crystalline counterparts, amorphous alloys exhibit distinct mechanical, physical, and chemical characteristics such as high strength, excellent corrosion resistance, high surface reactivity, and rather homogeneity at the subnanometer scale. , In amorphous alloys, the atoms are thermodynamically unstable and the atomic coordination numbers are typically unsaturated, allowing more active sites for electrochemical reactions to occur . The as-described characteristics of amorphous alloys endow HER catalytic properties that are better than those of the crystalline materials.…”

Interface Characteristics of Tungsten-Particle-Reinforced Zr-Based Bulk-Metallic-Glass Composites with Different Tungsten Particle Sizes

“…Bulk metallic glass (BMG) is a solid alloy characterized by long-range disorder and short-range order, formed through rapid cooling of the molten alloy. BMGs exhibit exceptional mechanical, physical, and chemical properties due to the absence of common defects found in crystalline alloys, such as dislocations, crystal boundaries, and segregation [1][2][3][4][5][6]. Zr-based bulk metallic glass (Zr-BMG) possesses remarkable glass-forming ability and excellent attributes such as high strength, hardness, wear resistance, and corrosion resistance, thereby garnering significant attention.…”
