Part of:


The paper considers the hot rolling of the metastable Fe-16Cr-4Mn-4Ni-0.05C-0.17N austenitic stainless. The understanding the recrystallization behaviour during the hot rolling process is required to optimize the hot rolling schedule. Therefore, the dynamic and static recrystallization behaviour was investigated by the compression tests using the Gleeble HDS V40. Each of those recrystallization behaviours was described by appropriate kinetics equations based on the obtained experimental results. The effect of the grain size on the recrystallized fraction was also taken into account. Furthermore, the numerical simulation with integrating these kinetics equations was performed using the Simufact.forming software. Moreover, the means flow stress (MFS) in dependence on the recrystallization behaviour and temperature state was analysed. The results of the numerical simulation were further validated by experimental data, which were obtained from the labour continuous hot rolling of the investigated metastable austenitic steel.
