Abstract
Recent studies on localized corrosion of corrosion-resistant metals and alloys are reviewed from the viewpoint of the development of new techniques that enable in situ and real-time observation of changes in morphology and solution chemistry during the initiation process of localized corrosion. Some examples of application of the new techniques are shown, focusing on the initiation of pitting, crevice corrosion and stress corrosion cracking on stainless steels.
