摘要
Single stage and double stage interrupted hot compression tests for physical simulating hot rolling have been carried out on the THERMECMATSTOR Z simulator for 00Cr20Ni18Mo6Cu[N] austenitic stainless steel under high temperature (1223～1373 K) and various strain rates (0.1～60 s -1 ). The high temperature mechanical behaviors and microstructure evolution of the steel were studied. The activation energies of hot deformation and dynamic, static and metadynamic recrystallization were calculated. Serials of perfect flow stress model considering dynamic recrystallization were established. The predicted result by the model was well agreed with the experiment data. The kinetics of metadynamic and static recrystallization had also been determined.
