AbstractThe corrosion of austenite and delta-ferrite phases and the respective phase boundary was investigated in unirradiated and proton-irradiated 308 L stainless steel weld metal in a simulated-PWR environment. The results revealed that the inner oxide thickness was increased by irradiation for austenite but was largely unaffected for delta-ferrite. This behavior was attributed to the fact that irradiation generated numerous structure defects in austenite, but not in delta-ferrite. Following the 3-dpa (displacements per atom) irradiation, enhanced corrosion of delta-ferrite/austenite phase boundary occurred due to the irradiation-induced Cr-depletion. M23C6 carbides along the phase boundary further enhanced corrosion regardless of the irradiation condition.
