... on the corrosion pit morphologies or stress groove geometries observed on the steel surface in the early stages of SSC. However, it remains unclear whether the crack-like corrosion morphologies, known as trenches or fissures, form in low-alloy carbon steels containing Ni cause failure or not. In this study...

... . This elongated corrosion pit is often called stress groove or fissure and cause a discussion on whether it is a crack or a pit. Pargeter ¹⁷ proposed a flow chart to differentiate between a crack or a pit, or a “no crack”. Recently, Anderson ¹⁸ proposed more detailed flow chart...

...Abstract Sulfide stress cracking (SSC) occurs in steel exposed to sour environments. Ni promotes the formation of a crack-like corrosion morphology (so-called stress groove or fissure), which accelerates the SSC; however, the mechanisms underlying fissure formation and growth are not fully...
