Abstract By using of the super element model in association with the LFG model, the equilibrium concentration of xγ/αC, driving force for pro��eutectioid ferrite and pearlite transformation, ΔGγ→α+γ1 and ΔGγ→α+cem, and thermodynamic equilibrium temperature of Ae3 and Ae1 were calculated for TRIP steel, in addition, the influence on TRIP steel of different chemical composition and hot deformation conditions was discussed. The predicted and measured Ae3 and Ae1 for un��deformed TRIP steel have good agreement, which shows that the calculations on phase equilibrium temperature in the paper is sufficiently accurate and reliable.
