High temperature oxidation behaviour of Fe–Al–C alloys: an overview

Carbide containing dual phase iron aluminide offers two-fold benefits; it posses high temperature strength and high resistance to probability of hydrogen embrittlement compared to single-phase iron aluminide. In this paper, we summarise the recent developments related to the oxidation behaviour of Fe–Al–C alloys. Emphasis is placed on the each variables of the system C, Al and temperature, and tried to differentiate the oxidation behaviour between Fe3Al/α and Fe3AlC phases while reviewing the oxidation resistance of Fe–Al–C alloys.
