Abstract
A method for predicting the ideal strength of metallic glasses based on materials properties---without fitting parameters---is presented, and its accuracy demonstrated for multiple alloys. The theoretical basis for these predictions is the stress-activated transformation of short-range ordered atomic structures into flowing amorphous interfaces with the properties of a supercooled liquid. Our theory for pure metals is extended through a regular solution model in which the enthalpy of fusion is mollified by approximate changes in coordination number between the solid and liquid phases. Additional parameters come from empirical material properties such as density, heat of fusion, and melting temperature.
