Extreme rejuvenation and softening in a bulk metallic glass

open access: yesNature Communications, 2018
Deforming metallic glasses can rejuvenate them to higher energy states, but only in the shear bands where deformation is usually concentrated. Here, the authors use a notched setup to suppress shear banding and promote significant bulk softening of a ...
