摘要

The oxidation behavior of Fe_3Al at 1000 deg. C in air was studied by thermobalance, scanning electron microscope (SEM) and X-ray diffraction (SRD). It was found that the oxidation kinetics approxi- mately follows the parabolic law; the oxide scale consists of Al_2O_3 and a little amount of Fe_2O_3; and three oc- curs transgranular internal oxidation. Based on the analyses of the oxide scale and the matrix, and internal oxi- dation model was proposed, which considers the effect of the long-range ordered structure of Fe_3Al on its high- temperature oxidation.
