Some numerical models such as central atoms model (CAM) and superelement model were used to si mu-late the thermodynamics of austenite decomposition in the Fe-C-Mn-Si TRIP (transformation induced plasticity)steels . Thermodynamic calculations were carried out under a para-equilibrium (PE) condition. The results showthat certain silicon content can accelerate the polygonal ferritic transformation andincrease the volume fraction andstability of retained austenite by retarding the precipitation of carbides during the bainitic transformation.
