title = "Influence of localized deformation on irradiation-assisted stress corrosion cracking of proton-irradiated austenitic alloys",
abstract = "Localized deformation (induced by low stacking fault energy (SFE) and/or irradiation damage) may play a key role in IASCC susceptibility of stainless steels. Three model alloys (UHP-304, 304+Si, and 304+Cr+Ni) having a spread in SFE and previously measured susceptibility in simulated LWR environments were selected for this study. Two batches of samples were irradiated with 3.2-MeV protons at 360̊C to 1.0 and 5.5 dpa respectively and then incrementally strained in 288°C Ar atmosphere to 3%, 7% and 12%. After each strain level, channel height, width and spacing were quantified. The degree of localized deformation at 3% strain in both 1.0 and 5.5 dpa samples was considerably higher in the base-304 and 304+Si alloy than the high- Cr+Ni alloy, consistent with the cracking at 5.5 dpa where the base-304 and 304+Si alloys failed via IG cracking while the 304+Ni+Cr alloy was resistant to cracking. The degree of localized deformation, which is affected by irradiation dose and SFE, is closely related to the observed IGSCC.",
