| Abstract: | A prediction model of phase transformation from thermodeformed austenite to ferrite,pearlite and bainite is given in this paper.The model was developed on the thermodynamic basis of super-element and LFG models and the kinetic basis of Cahn's transformation theory and Scheil's superposition rule.The effects of deformation,cooling rate and finish rolling temperature on phase transformation are discussed in this paper. |

| Keywords: | austenite transformation prediction model deformation cooling rate finish rolling temperature |
