Structural evolution of an Au-based bulk metallic glass (BMG) after severe plastic deformation (SPD) was investigated The newly formed glass contains high-density shear bands, a reduced ordering and a concomitant excess free volume Moreover, it exhibits a less changed local structure even in the supercooled liquid region, but a reduced thermal stability reflected in an accelerated crystal nucleation and growth process These results s
