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