| Abstract: | The experiment was carried out on Thermecmaster Z simulator by means of single stage. The deformation activation energy of C Mn steel was calculated.The physical metallurgical phenomena such as dynamic recovery, dynamic recrystallization as well as their internal evolution caused by hot deformation were investigated. The math models of flow stress for C Mn steel were established. |
