On the basis of superelement model,Cahn's transformation kinetics theory and Scheil's additivity rule,the CCT diagrams and transformation kinetics in low carbon steel were predicted considering both undeformed and deformed conditions.The influence of deformation on phase equilibria and transformation incubation period was evaluated quantitatively.The recrystallization kinetics and the evolution of dislocation density were calculated during continuous cooling.The results show deformation considerably shortens transformation incubation period,accelerates transformation kinetics and makes CCT curve shift leftwards.The calculated CCT diagrams and the volume fraction of each phase are in good agreement with measurements.
