and strain 10% 〜50% at 950 〜1 200 °C has been carried out by using Gleeble-1500 thermo-mechanical simulator. Results show that low strain rate and large strain are favorable to the occurrence of dynamic recrystallization of test steel. The calculated dynamic recrystallized activation energy of the steel YF45MnVS at 950 〜1 200 ℃ is 299. 55 kJ/mol.
