These features can develop a sharp sulfide stress crack at their bottom under certain conditions, which are still not fully understood. In this second and final part, the effect of the electrochemical...

... of the sulfide films that form on the steel’s surface at OCP. The rupture of this film due to tensile stress promotes the nucleation of deep planar features, referred to as trenches, which can act as sulfide stress crack initiators. Trenches were observed exclusively in stressed, Ni-containing specimens...
