Abstract

This study shows that metallic glasses can be rejuvenated (taken to higher energy states with more plasticity) by thermally cycling them at relatively low temperatures (well below the glass transition temperature); this is attributed to the effect of intrinsic structural inhomogeneities in the glassy state, which translate into localized internal strains as the temperature is cycled and the different regions expand and contract by different amounts.
