Abstract
A physical mechanism and a mathematical model of forming a pore superlattice on irradiation is suggested. The interaction of an individual vacancy with the elastic stress field created by all excess vacancies is taken as a basic one. It is demonstrated that when the vacancy concentration exceeds a certain critical value (proportional to the temperature), the instability arises resulting in the formation of the pore superlattice. The dependences of the superlattice period on the properties of the material and irradiation conditions are established. The results obtained are in satisfactory agreement with the available experimental data.
