Application of phase-field modeling to irradiation effects in materials

This paper summarizes the recent advances in phase-field modeling in the field of radiation materials science. Conventional phase-field equations are first presented for the thermodynamic and kinetic description of irradiation-induced defects. Results of homogeneous and heterogeneous void and gas bubble evolution are then discussed, including gas bubble nucleation and growth, internal bubble gas density fluctuations, void lattice formation, and intergranular bubble dynamics. Finally, future directions for phase-field modeling in this field are addressed, with the intention of highlighting areas that require focused consideration that are necessary for the continued improvement and applicability of the method for radiation problems.
