| Abstract Scope |
Stress corrosion cracking (SCC) is an insidious degradation phenomenon that is often difficult to identify and mitigate due to a dependence on a range of variables across materials science, mechanics, and electrochemistry. Recent advances in modern microscopy have allowed for better identification of SCC mechanisms in specific material-environment conditions, including development of predictive capabilities. In this overview, examples will be provided to demonstrate the application of correlative microscopy techniques to elucidate SCC mechanisms. This will include SCC of Ni-based alloys and stainless steels in high temperature (~300 °C) aqueous solutions, and Cu in ambient condition nitrite solutions. A multi-technique approach is applied, ranging from the micro-to-nanoscale and including a combination of electron microscopy and surface science techniques, to identify SCC mechanisms. This knowledge is then directly applied to predict precursors that may be present prior to the onset of engineering-level degradation, which can be identified using similar correlative microscopy methods. |
