Abstract

A model is advanced for the discontinuous propagation of a Portevin-Le Chatelier deformation band in tensile tests. The glide resistance is assumed to be a superposition of a time-independent strain hardening component and a time-dependent solute hardening component. The amplitude of the stress serrations, the strain increment across the band, and the propagation of the band per serration are calculated as a function of the work-hardening parameter, and material and machine parameters. The predictions of the model are found in good agreement with measurements.
