Research on Dynamic Recrystallization Behavior of 20CrMo Alloy Steel during Hot Deformation

摘要：

　　Hot compression deformation test were conducted on 20CrMo alloy steel on a Gleeble-1500D thermal simulator when the deformation amount was 30%,temperature ranged from 1273 to 1373K and strain rate from 0.0015 to 0.015s-1.Flow stress curves were obtained under different deformation conditions; DRX activation energy was calculated using mathematical method.The starting time of DRX was analyzed and the kinetic equation of DRX was established.This model fits well with test data and can meet the requirement of engineering calculation.
