Highlights • Tg correlates with eutectic or peritectic temperature of main components. • Tg is mainly determined by their solvent of two base components. • The weakest link in metallic glass is solvent and solvent bond of two base components.

Abstract We report that the glass transition temperature (Tg) of a variety of metallic glasses (MGs) correlates with the eutectic or peritectic temperature of two main components corresponding stoichiometric proportion in their binary phase diagram. The correlation suggests that the Tg of MGs is mainly determined by their solvent of two base components, which have composition close to the eutectic and peritectic points in the binary phase diagram and the weakest link in amorphous structure. The results have implications for understanding the structure and glass transition in MGs and for predicting and designing metallic glasses with a desirable Tg.
