View License Agreement Predicted irradiation-induced enrichment of silicon and depletion of chromium at grain boundaries were consistent with measurements of ion-irradiated stainless steel grain boundary microchemistries. The calibrated solute drag mechanism for silicon enrichment and the inverse-Kirkendall mechanism for chromium depletion were then used to predict behaviors for neutron irradiation conditions relevant to irradiation-assisted stress corrosion cracking. A simple crack chemistry model illustrated how irradiation-induced chromium depletion might affect intergranular corrosion as a function of dose. | ||
