Abstract

A constitutive description of the stress-strain curve in hot deformation based on a rate equation is proposed. The activation parameters in the equation were found to decrease as deformation proceeded and a linear relationship with the work hardening rate was established. Introduction of the work hardening rate, which is representative of the state of the material, into the constitutive equation, enabled prediction of material response under changing process conditions. Typical results are presented. A mechanistic interpretation of the results is proposed.
