| Abstract Scope |
Austenitic 304L stainless steel is the main material used for spent nuclear fuel storage canisters and is susceptible to pitting and stress corrosion cracking under certain conditions of humidity, temperature and salt chemistry. In this investigation, the effects of laser shock peening (LSP) with and without an ablative coating on the corrosion resistance of sensitized 304L stainless steel (SS) was studied using DLEPR to evaluate the degree of sensitization (DOS) and susceptibility to intergranular attack (IGA). Characterization of the microstructure was conducted using SEM, TEM, EBSD and XRD. The results indicate a notable impact of the LSP process on the susceptibility of 304L SS under corrosive conditions. The specific complexities as effected by the varying LSP treatments (residual stress, deformation-induced martensite, etc.) and their aforementioned effects will be presented and discussed. |
