Description

The objective of this work is to determine the susceptibility of a fusion-relevant alloy to irradiation-assisted stress corrosion cracking (ISACC) by performing slow strain rate tensile (SSRT) testing of fusion spectrally-tailored materials in aqueous environments. Specimens of a type 316 stainless steel (SS) that had been irradiated in the fusion spectrally-tailored MFE-6J/7J experiments in the Oak Ridge Research (ORR) to 7.4 dpa at temperatures of 400, 330, 200, and 60C were SSRT tested in a recirculating autoclave system in oxygenated, high-purity water. Complete intergranular (IG) failure was observed only for the specimen irradiated at 400C. Only 10% IG failure was observed for the 330C irradiated specimen and no IG failure was observed for the specimens irradiated at 200 and 60C
