Abstract
The jerky flow for a Zr-based bulk metallic glass is analyzed, based on the accumulation and dissipation of the elastic energy, and the temperature rise within the shear bands. The formation of a viscous layer results in the tiny disturbance among the jerky flows, which makes the jerky-flow kinetics inhomogeneous. The parameter, the jerky-drop-stressing speed, is used to characterize the shear-banding kinetics. An increased shear-banding speed dominates upon loading, which is in agreement with the change of the free volume.
