We, for the first time, propose a phase-field model to simulate the evolution of void ensembles under irradiation. The model takes into account one-dimensional migration of self-interstitial atoms (1-D SIAs), vacancy diffusion, the generation and reaction between SIAs and vacancies as well as the nucleation of voids. Simulation results show that a void lattice forms when the mobility of the 1-D SIA is four orders of magnitude larger than that of the vacancy mobility. A high generation rate of interstitials during displacement cascades delays the formation of a void lattice.
