Stress Corrosion Cracking (SCC) is a materials degradation mechanism known to affect stainless steels and can lead to sudden failure of normally ductile metals. The structural and functional integrity of materials used in corrosive environments is a critical concern as unexpected failure could have severe consequences. To explore the mechanical behavior of crack formation in a corrosive environment, the current research will be done to understand how SCC could possibly perform as a failure mechanism with a focus on materials selection, materials properties, and microstructure changes as it pertains to SCC. A high-throughput, small-sample testing apparatus has been designed and constructed to test for materials susceptibility to stress corrosion cracking. The study will be to gain better insight on the susceptibility of SCC in 304L stainless steel. Scanning Electron Microscopy will be used to verify the SCC failure mode. The goal of this work is to develop an effective, reliable method of detection given the influences of SCC on 304L. The development of such a method could help ensure safer operational lifespans of critical performing parts of the nuclear fuel cycle. The commercialization potential of a SCC sensor based on this research was also considered through a collaboration with the College of Business and Economics (COBE).
