Abstract

The isothermal oxidation of Fe-30Al alloys in 1 atm of pure O2 at 973 K and 1173 K was investigated. Fe-30Al alloy oxidized slowly at 973 K but much faster at 1173 K, especially during the transient oxidation stage. The mass gain of the alloy at 973 K after 24 h oxidation is only about 0.1 mg/cm2, much smaller than the corresponding value of 0.6 mg/cm2 at 1173 K, indicating that the oxidation resistance at 973 K is much better than that at 1173 K. The scales formed at both temperatures are mainly composed of Al2O3, coupled with a little Fe2O3. It is obviously that the protective Al2O3 layer formed on Fe-30Al at 973 K show better homogeneity and integrality than that at 1173 K.
