SUMMARY A wide range of scaling processes can occur during the high temperature oxidation of FeCr alloys. Here we discuss the relative merits of using alternative transmission electron microscopical (TEM) techniques, as applied to edge‐on foils, for characterizing some of the different diffusional and microstructurally limited processes which occur, in particular at oxide and metal‐oxide boundaries. We give results for interfaces in wüstite, which is formed very rapidly on pure iron, as well as for the more protective FeCr spinels and sesquioxides, as grown on FeNiCr alloys in both air and 1%C0–C0 2 .
