Abstract We present a model which predicts the critical free volume concentration of shear banding instability in metallic glasses (MGs). From the stability map, this model demonstrates that the prediction of shear band thickness is valid only for a short time after shear instability, and the diffusion of defects should be included in the mature shear band in MGs. The results agree well with the experimental observations and simulations.
