摘要：

The meta-dynamic recrystallization behavior of SCM435 steel was studied on the MMS-200 thermal simulation machine through the double-pass compression experiment. The effects of the deformation temperature, the strain rate, and the initial austenite grain size on meta-dynamic recrystallization were analyzed. Based on the test result, the kinetics model of the meta-dynamic recrystallization of SCM435 steel was established, and the obtained activation energy was 242.3kJ/mol. The results showed that the meta-dynamic recrystallization fraction X-m of SCM435 steel increased as the deformation temperature and the deformation rate increased, decreased as the initial grain size increased, and increased as the time interval increased.
