Phase field approach has been successfully used to predict the microstructure evolution in many important materials processes such as solidification, precipitation, and multiferroic domain evolution. The deformation due to lattice mismatches and applied stresses can be one of main driving forces for microstructure evolution. In order to capture the impact of non-uniform deformation of polycrystalline on microstructure feature, crystal plasticity formulations were developed for considering crystal orientation and dislocation slip systems of each grain. We will present an efficient method to find the elastic-plastic solution in polycrystalline and a phase field model to integrate crystal plasticity and microstructure evolution. The developed model has been used to study 1) effect of the microstructures in bimodal and dual phase polycrystallines on elastic-plastic deformation and 2) effect of plastic deformation on dynamic recrystallization. Its potential application in optimizing material fabrication processes and predicting creep deformation and fracture will be discussed.
