Abstract
An innovative analytical model of radiation-induced segregation (RIS) in dilute alloys is presented. The approach is based on non-equilibrium segregation theory and can be extended to cover a multiplicity of sink types in a wide variety of metallic matrices. The model circumvents the requirement for complex mathematical procedures inherent in current rate theory analyses of RIS. Calculations are made for nickel segregation to grain boundaries in α-Fe and γ-Fe and for zinc segregation in silver. Adequate fits between the limited available experimental surface segregation data and the model predictions are obtained. The analysis is used to deduce trends in grain boundary segregation in austenitic and ferritic steels to provide insight into materials selection for nuclear plants to meet requirements for minimal RIS.
