An experimental study of dynamic recrystaUizatuon of austenite SWRH82B steel was carried out using Gleeble-2000 thermal simulator. The effects of deformation temperature and deformation rates on the dynamic recryatallization process were studied by the experimental dams. The relation between dynamic recrystallization of austenite SWRH82B steel and parameter Z was analyzed. The results show that the dynamic recystallization occurs when deforming at high-temperature, low-deformation rate and low parameter Z.
