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