WebThe mechanism of stress corrosion cracking (SCC) involves a very complicated sequence of corrosion and fracture. It has been shown that, for some materials, fine pitting is needed to start the activity. Further progress is then a process alternating between corrosion and mechanical cracking until the material fails completely. WebJan 11, 2024 · The mechanism for caustic cracking is not fully understood but appears to be related to selective dissolution. In pits where cracking initiates, there is often found a nanoporous layer enriched in Fe and Cr. Mo may also be observed if present in the alloy.
