[Abstract]:The plastic mechanics of crystals is based on dislocation theory, which can relate the plastic deformation behavior of materials to the changes of microstructure, and is widely used in the study of deformation texture. The plastic deformation mechanism of magnesium alloy is briefly described, and the application and development of crystal plastic mechanics in the evolution simulation of magnesium alloy texture are introduced. The Taylor model, elastic-plastic self-consistent model and viscoplastic self-consistent model are emphasized. The research process and application status of elasto-viscoplastic self-consistent model are reviewed. Finally, the problems existing in the application of the crystal plastic mechanics model in the evolution of magnesium alloy texture are pointed out, and the prospect of its application in the deformation texture simulation of magnesium alloy is prospected.
