| Abstract | The corrosion of unaged and 70 0 0-h thermally aged 308L stainless steel weld metals in simulated PWR primary water under aerated and deaerated conditions was investigated, involving the corrosion of austenite, 8-ferrite and 8-ferrite/austenite phase boundary. The results revealed that thermal ageing for 70 0 0 h had a limited effect on the corrosion behavior of 308L weld metal as it only increased the inner oxide thickness of 8-ferrite slightly under the deaerated condition. No obvious corrosion enhancement of 308L weld metal under the aerated condition was found compared to the deaerated condition regardless of the thermal ageing. Nevertheless, Cr-enrichment on the surface of oxide particles, dissolved regions at the metal/oxide interface and localized corrosion along the 8-ferrite/austenite phase boundary occurred under the aerated condition.
