Abstract

A mathematical model for predicting the transformation of proeutectoid steels during continuous cooling and the microstructure after transformation has been developed using time-independent equations of the transformation kinetics. The effect of chemical compositions on the transformation kinetics is considered in terms of nucleation and growth rates calculated theoretically with thermodynamic parameters. The transformations from austenite to ferrite, pearlite, and bainite during continuous cooling can be calculated by the model and good agreement between the calculated and measured results can be obtained. The effect of hot deformation on the transformation kinetics is also discussed.
