Size-dependent vitrification in metallic glasses
Nature Communications, 2023 Reducing the sample size can profoundly impact properties of bulk metallic glasses. Here, we systematically reduce the length scale of Au and Pt-based metallic glasses and study their vitrification behavior and atomic mobility.

Enhancing ductility in bulk metallic glasses by straining during cooling
Communications Materials, 2021 Bulk metallic glasses typically display limited ductility. Here, straining a bulk metallic glass during cooling from the supercooled region is shown to enhance bending ductility, attributed to the structure being pulled up the potential energy landscape.

Properties of bulk metallic glasses
Russian Journal of Non-Ferrous Metals, 2016 A relatively small number of revolutionary materials have been discovered in the field of physical metallurgy and metal physics in the last several decades, and bulk metallic glasses are among them. Their strength and hardness are considerably higher and their modulus of normal elasticity is considerably lower than that of crystalline alloys, which ...
