Abstract

The redistribution processes of non-equilibrium vacancies under the spinodal decomposition in a continuously irradiated solid solution have been considered. The consideration is carried out in the framework of the generalized Cahn–Hilliard model, which makes allowance for the structural disorder formation under irradiation. As the defect production rate increases, the spinodal decomposition processes are found to transform into the processes of vacancy pattern formation. It is shown that the formation of vacancy clusters is accompanied by the pattern selection processes. The decomposition and patterning kinetics, as well as the statistical distributions of solute and vacancy concentrations at various dose rates are studied.
