Abstract

The oxidation behaviour of Cr5Fe1Y(2)O(3) prepared by 2 different manufacturing techniques was studied in Ar/H(2)/H(2)O at 1000 C. Transmission electron microscopy (TEM) studies of alloy microstructure after oxidation revelated that the oxidation rate of the Cr-based oxide dispersion strengthend (ODS) material depends on the yttria content and distribution. Transport of Y from the alloy to the scale occurs through dispersions which become embedded in the inward growing scale and/or by transport of Y along structural defects in the alloy.
