Abstract Scope A physically based model describing both recovery and recrystallization and their couplings have been developed for deformed ferrite. The decrease in dislocation density has been modeled thanks to Friedel’s work. A new model was built to predict recrystallization kinetics inspired by the nucleation model developed by Zurob et al. for austenite at high temperature. The nucleation flux is calculated in accordance with SIBM theory and the growth of new grains is governed by a mobility equation. Only the mean radius of recrystallized grain is calculated by considering the competition between nucleation and growth processes. Finally, the recrystallized fraction is calculated using the extended volume theory. The parameters and mobility functions were calibrated to best reproduce experimental trends reported on cold-rolled ferrite-pearlite steels during continuous annealing. The prediction of the model has been then utilized to assess the effect of the cold-rolling ratio on recrystallization kinetics with a very reasonable agreement.
