Summary

An austenitic stainless steel alloy that contains 4.5 wt% Al was oxidized in air at 1200°C. The resultant oxide layer, characterized by Auger, EDS, and TEM, was found to be primarily α-Al2O3, with a thin outer layer of mixed oxides of Fe, Cr, and Ni. The crystalline α-Al2O3 had a grain size of between 0.2 and 0.5 μm; the mixed oxide had a grain size approximately one-hundredth the size of the Al2O3 grains. The Al2O3 film thickness was determined by Auger depth profiling and TEM cross-section imaging to be between 1 and 3 μm.
