Abstract
The microstructural evolution with time and dissolved oxygen of the oxide film formed on 15–15Ti austenitic stainless steel during the early oxidation stage in steam at 500 ℃ was studied using multiple test instruments such as transmission electron microscopy (TEM). A triplex oxide structure with an outer Fe-rich layer, an inner Cr-rich layer, and a Ni-rich transition layer was confirmed for all samples. The relationship between corrosion resistance and oxide structure is discussed. One mechanism for pore formation in the inner oxide layer of austenitic steel is proposed based on the spatial distribution and migration behavior of Ni during oxidation.
