The figure shows a cross-section of the specimen of austenitic stainless steel S32654 after oxidation at 900 °C for 1 h. The light gray area is the matrix, and the dark gray area is the oxide layer formed by the oxidation. The blue line means the distribution of Mo element along with the yellow line. The more detail can be found on the source.
