摘要：

A TEM and STEM examination has been carried out of cross-sectioned specimens of convoluted chromia scale formed by oxidizing chromium at 950-degrees-C. Sulfur was detected at the oxide/metal interface and the oxide grain boundaries (apart from low-angle grain boundaries), but not within the oxide grains. These results are consistent with the "sulfur effect" theory.
