| Abstract Scope |
Austenitic stainless steels are commonly used in engineering applications, while these materials exhibit excellent corrosion and fracture resistance they are susceptible to stress corrosion cracking in aggressive environments. Systematic studying of the sensitivities of this behavior and the governing mechanisms is lacking. This work aims to establish the relative role of dissolution and H-embrittlement on the governing damage physics for 304L. Fracture mechanics testing of the SCC behavior will be performed in discrim-inating environments and crack tip analysis of the local plastic damage state and the ex-tent of strain induced martensite transformation will be performed. To decouple the role of anodic dissolution and H-embrittlement tests will be conducted where (1) the propensity for anodic dissolution is held constant and the level of H-embrittlement is varied (via H recombination poisons), and (2) where the H-embrittlement level is con-stant but the propensity for anodic dissolution is varied (via targeted polarization). |
