High-temperature oxidation behavior of iron-chromium-aluminum alloys

The detailed oxidation behavior of Fe-10Cr alloys, containing aluminum in the range of 2-8% by weight, was studied in pure oxygen at 1 atm pressure. The investigations were performed over the temperature range 950-1050 °C under cyclic conditions (3-hr cycles) in each case. The cyclic-oxidation resis...
