Interplay of Microbiological Corrosion and Alloy Microstructure in Failures of Advanced Stainless Steels and their Weldments in Marine Environments. The proposed research program investigates the role of microbiologically-induced corrosion (MIC) on stress corrosion cracking (SCC) of weldments of advanced stainless steels (SS).

The proposed research program investigates the role of microbiologically-induced corrosion (MIC) on stress corrosion cracking (SCC) of weldments of advanced stainless steels (SS). Extensive premature SCC failures of SS weldments have lately become increasingly significant in Australian marine industry, following the inability of advanced SCC-resistant SS to alleviate failures. Inconsistencies in SCC data call for an improved understanding of the role of MIC on SCC, particularly because recent failure analyses have indicated a profound role of microbiological activity on localised corrosion (viz., pitting) of stainless steels and their weldments, as well as because pitting is known to facilitate SCC initiation.Read moreRead less
