Study on the Dynamic Recrystallization of Austenite in the Isothermal Compression of 300M Steel

Abstract:

The 300M steel was isothermally compressed on a Gleeble-3500 simulator at the deformation temperatures ranging from 1123 K to 1473 K, the strain rates ranging from 0.1 s^-1 to 25.0 s^-1 and a strain of 0.51. The morphology of austenite grains in the isothermally compressed 300M steel was observed using an OLYMPUS PMG3 microscope. The experimental results show that the deformation temperature and strain rate have an interaction effect on austenite grains in the isothermally compressed 300M steel. Dynamic recrystallization occurs more easily at high deformation temperature and low strain rate. Dynamic recrystallization occurs completely and the coarse grains occur at the deformation temperature above 1413 K. The austenite grain size increases as the deformation temperature increases while it decreases as the strain rate increases.
