Abstract

Homogeneous deformation in metallic glasses is facilitated by high temperature and low strain rate. Here, the window for homogeneous deformation is expanded by the application of a pulsed current during tensile loading of a Zr55Cu30Al10Ni5 metallic glass, attributed to dynamic rejuvenation.
