Abstract

Based on the theories of Seeger's dislocation pile-up and Orowan's dispersion hardening, the hardening behavior of single crystals was found to obey Prager's kinematic hardening rule. Under single slip, yield surface moves along its normal while under multislip it moves along the direction of incremental stress. The theory developed is consistent with the Bauschinger effect; it is also in good agreement with the observations of Edwards and Washburn on the latent hardening of zinc, cadmium and copper crystals.
