Abstract

Static recrystallization (SRX) behavior of a nitrogen-alloyed ultralow carbon austenitic stainless steel was studied on a Gleeble-1500D thermal-simulator by two-step hot compression tests. Deformation temperatures of 1173-1473 K, deformation strains of 0.051-0.105, strain rates of 0.01-1 s−1, and inter-step times of 1-100 s were selected as the deformation conditions to investigate the effects of deformation parameters on SRX behavior. Besides, the influences of initial grain size on SRX behavior were studied. The results show that deformation temperature and strain have greater influences on SRX behavior than strain rate and initial grain size. Based on true stress-true strain data obtained from the experiments, SRX kinetics equation was determined. In addition, the established SRX kinetics equation was introduced into finite element simulation software DEFORM-3D to perform the two-step compression deformation. Furthermore, SRX kinetics equation was modified for improving the accuracy of finite element simulation, and the modified SRX kinetics equation was verified.
