A new simulation model of recrystallization processes is proposed in this report. The model is based on nucleation and grain growth theory, and is combined with the deformation enegy thoery, which estimates the effect of plastic deformaiton on metallurgical phenomena by the generalized deformation energy. In this model, dispersion of grian growth rate is also taken into account, and a new differential equation that expresses grain size variation is proposed. The model was verified by numerical simulation. The calculated grain size variation showed qualitically proper characteristics as static recrystallization process. The model was also adopted to ABAQUS, and a forging and annealing process was simulated by the FE analysis.
