An overview of radiation-induced solute redistribution process in ion bombarded alloys is presented and some applications to damage correlation studies are described. The type and amount of solute redistribution which occurs and its temporal and spatial dependence are affected not only by the target material and irradiation conditions, but also by the mass and energy of the incident ion. Because of the sensitivity of radiation damage effects in alloys to changes in composition, an understanding and an appreciation of the magnitude of these redistribution effects are essential for a proper interpretation and correlation of damage microstructures produced in alloys by different bombarding ions. Furthermore, once understood, these redistribution effects can be used to quantify differences in the calculated atomic displacement rates and the net production rates of freely migrating defects for different ions. Such information is a prerequisite for quantitative damage correlation, and requires a quantitative understanding of the dose-rate dependence of solute redistribution effects. Recent experimental and theoretical studies which provide the basis for such applications of solute redistribution effects are discussed.
