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 Xm 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.
