Abstract
Recently, Iron aluminide compounds have attracted considerable interest due to their attractive physical and mechanical properties such as high-temperature applications, good oxidation and sulfidation resistance, low density and low production cost. In the present research, the following methodology was undertaken: first, FeAl and Fe2Al5 were synthesized. Then the Fe2Al5 and FeAl oxidation behavior was investigated in the air for 2–60 h at 850 °C. It was found that FeAl is more resistant to the oxidation compared to Fe2Al5. The FeAl oxidation rate reaches a plateau in higher temperatures while Fe2Al5 oxidation curve has an upward trend with the fluctuation. The reason for such a behavior is the difference in alumina growth mechanism.
