中文摘要：
The formation and evolution of deformation texture in polycrystalline materials are studied by phase-field dynamic model.In addition,the driving force of texture evolution is also discussed.In this model,grains with different orientation are defined by a set of continuous non-conserved order parameter fields.Simulation results show that grains with preferred orientation grow at the expense of those with unfavorable orientations.It is more important that,elastic potential rather than elastic energy plays a crucial role in the evolution of texture whether the polycrystalline system is subjected to uniaxial stress or shear stress.
