The static recrystallization behavior of 25CrMo4 mirror plate steel has been determined by hot compres-sion testing on a Gleeble 1500 thermal mechanical simulation tester.Compression tests were performed using double hit schedules at temperatures of 950-1 150°C, strain rates of 0.01-0.5 s-1 , and recrystallization time of 1-100 s.Results show that the kinetics of static recrystallization and the microstructural evolu-tion were greatly influenced by the deformation parameters (deformation temperature, strain rate and pre-strain) and the initial austenite grain size.Based on the experimental results, the kinetics model of static recrystallization has been generated and the comparison between the experimental results and the predic-ted results has been carried out.It is shown that the predicted results were in good agreement with the ex-perimental results.
