Abstract

Abstract In this study, we simulate the radiation-induced phase transition in the binary alloy employing the modified Cahn–Hilliard (CH) equation that accounts for the process of radiation-enhanced diffusion, ballistic mixing, and compositional fluctuations. The influence of displacement rate on the dynamics of the average radius, number density, nucleation rate, and volume fraction of the second phase is discussed. Also, the mechanism of precipitate vanishing under irradiation condition is revealed.
