The experimental data and models of radiation-induced segregation are presented. The mechanism and
efficiency of the radiation-induced segregation depend on several factors: the irradiation temperature, the
concentration and size of atoms of impurity, the presence of additional impurity, etc. The majority of models
which describe the radiation-induced segregation, include a system of kinetic equations for the various kinds of
point defects and alloy atoms. The models differ from each other in a set of the types of defects and calculation
parameters.
