“…During the last decades, bulk metallic glasses (BMGs), also termed as bulk amorphous metals, have attracted considerable scientific and industrial interests from materials science community due to their excellent physical, chemical, and mechanical properties (Greer, 1995;Schuh et al, 2007;Huang et al, 2009;Huang et al, 2010a;Zheng et al, 2011;Han et al, 2018;Liu et al, 2018;Lu et al, 2018;Li et al, 2019). Owing to their disordered atomic configuration differing from conventional crystalline materials, BMGs often offer ultrahigh strength, excellent wear/corrosion resistance, and high elastic limit, typically superior to those of their crystalline counterparts (Huang et al, 2010b;Edwards et al, 2013;Huang et al, 2014a;Louzguine-Luzgin et al, 2017;Yang et al, 2020).…”

Bulk metallic glasses (BMGs) often offer excellent physical, chemical, and mechanical properties such as high strength, high hardness, and good wear/corrosion resistance, stemming from their unique atomic configuration. These properties enable them to be a potential engineering material in a range of industrial applications. However, the wear behaviors must be considered in structural applications. Here, the wear tests of a TiZrNiCuBe bulk metallic glass at high temperatures were carried out. As the testing temperature increases, the wear rate of the studied BMG sample gradually decreases and the sample surface becomes smoother. Meanwhile, a higher applied normal load causes a higher wear rate. The wear mechanism evolves from the abrasive to adhesive mode with increase in the testing temperature. The results obtained here could shed more insights into the deformation mechanism of BMGs and thus extend their industrial uses in high-temperature environments.
