Abstract
In this chapter, the basic point defect kinetic equations and the solutions in different temperature and microstructural regimes are presented. The transient and steady-state solutions to the point defect kinetic equation are then described. Equations for radiation-induced segregation (RIS) are developed by adding diffusion terms to the point defect kinetic equations and allowing for multiple constituents in an alloy. The solution to the RIS equations are developed and segregation in austenitic Fe-Cr-Ni alloys is described in detail to provide insight into segregation behavior. Finally, a simple model that includes composition dependent diffusion parameters is described. This composition-dependent model improved the ability of RIS models to predict segregation in Fe-Cr-Ni alloys.
