Abstract
The initiation of stress-corrosion cracks in austenitic
stainless steels in hot chloride solutions, hot
oxygenated water, and room-temperature acid solutions has
been examined. The initiation processes have been
characterized by electron microscopy and X-ray
microanalysis. Corrosion crevices consisting of Cr-rich
corrosion sponge have been found in all the systems
studied. The electrochemical reactions of
corrosion-sponge formation are clarified. Some effects of
the underlying metallurgical structure on
corrosion-crevice morphology are also presented. Finally,
the differences between the crack initiation and
propagation stages are discussed.
