Abstract
We report a universal scaling law, , that uncovers an inherent relationship of the yield strength with the glass transition temperature and molar volume of metallic glasses. This equation is derived from fundamental thermodynamics and validated by various metallic glasses with well-defined yielding. The linearity between and demonstrates the intrinsic correlation between yielding and glass-liquid transition, which contributes to the basic understanding of the strength and deformation of glassy alloys.
