| Research Abstract |
A phase-field model is constructed from conservation laws corresponding to the energy principle. The conservation laws are derived by microscopic physical quantities on the crystal lattice scale. A static recrystallization phenomenon is calculated by the presented model. Moreover, coupling the multi-phase-field model and the dislocation-crystal plasticity model, we construct a dynamic recrystallization model considering nucleation based on dislocation accumulation.
