Abstract

Relaxation is a key feature in glassy physics, and the strain-induced effects on relaxations in metallic glasses are of practical significance, yet still unclear. Through a contrastive combination of dynamical mechanical spectroscopy and linear-heating stress relaxation methods, we find that strain effectively facilitates the relaxation dynamics with divergent modulation behaviors in a wide temperature range for metallic glasses. Two loading modes are coupled with linear-heating, and we experimentally confirm the “temperature-strain equivalence”. Our results benefit for better understanding the unique effect of strain on relaxation and for providing guidance on applications of metallic glasses with improved performances at different temperatures.
