Abstract

We use large-scale atomistic simulations to study the work-hardening process that occurs when two metals slide against one another. Dislocations form at the interface between the work pieces and then migrate into the bulk. We examine the relationship between the velocity noise signature at the atomistic level and the number of dislocations present. We compare these signatures to those observed in a system of a single particle dragged through a lattice, where local melting can occur.
