Abstract
Solute diffusion occurs in the solid state through interactions between lattice defects and specific solute species. This article describes calculations and measurements of major solute diffusion parameters in irradiated austenitic stainless steels at temperatures below 500 °C. Calculated diffusivity parameters are shown to be in accord with high-temperature, thermal-diffusion experiments. The predictions are used to understand irradiation-assisted stress corrosion cracking as it relates to chromium depletion at irradiated grain boundaries.
