AbstractA model to predict the evolution of dislocation density following hot deformation is presented in this article. The model is validated by stress relaxation experiments on austenite at various temperatures. It is found that the activation energy for self-diffusion is the rate-controlling parameter determining the evolution of dislocation density, and hence the recovery rate. A methodology to control the softening experienced by high-temperature alloys is proposed. © 2011 Taylor and Francis.
