摘要

Using the acoustic emission method, we have determined the probability density distribution function of shear band lengths in a metallic glass and demonstrated its independence of stoichiometric composition of glass and experimental conditions. The power-law form of this distribution confirms independently the observed quadratic scaling in the time dependence of the rate of shear processes in metallic glass.
