“…The lower value for k p 2 than k p 1 and its occurrence at later stages of oxidation, beyond which the rate of oxidation becomes low, could indicate that it corresponds to the formation of aluminium oxide. The time taken for the transition from one mode of oxide formation to another in the present case is 200 h; other authors have reported this transition to occur within 25 h of oxidation in the case of Fe-7.5Al-0.65C alloy at the same temperature [22]. Nevertheless, it is becoming clear that the formation of Al 2 O 3 is crucial in the protection of Fe-Al alloys from oxidation and its formation depends on time and temperature of oxidation.…”

Iron aluminides produced by the electroslag refining technique, having the compositions: (1) Fe-16Al-1C, (2) Fe-10Al-1C, and (3) Fe-8Al-1C were used to investigate the effect of Al on the oxidation behaviour of the Fe-1C-Al system at 700 to 1000 C. Prior to oxidation studies, phase and microstructure of alloys were analysed. The carbide phase, Fe 3 AlC 0.69 , was found to be distributed in the Fe 3 Al matrix in alloy 1 and (Fe-Al) matrix in alloys 2 and 3. The low Al content alloys displayed inversion in the oxidation kinetics below 800 C, while, high Al content alloy displayed inversion phenomena at 1000 C. The mechanism involving inversion in oxidation kinetics was found to be different in the two cases. In the former, it was attributed to the preferential oxidation of Al, while in the latter, to the phase transformation within the Al 2 O 3 . Carbides in the alloy having low Al content showed instability during oxidation.

“…The other factor that can enhance the oxidation tendency of carbides is the presence of carbon. On oxidation, the carbide phases release CO/CO 2 [26,27]. This makes the oxide porous, which is less protective and vulnerable to oxygen diffusion.…”

“…No carbide-free layer could be observed in the alloy which was oxidized at 600 • C. In contrast, a carbidefree zone was found in the specimens after oxidizing at 800 and 1000 • C. The differences in oxidation behavior are controlled by the stability of the carbide at different oxidation temperatures. They also reported that the oxidation behavior of Fe-7.5Al-0.65C alloy oxidized at 600 to 900 • C for 24 h could be classified into two groups [66] . The change in the oxidation behavior observed between 600 and 700 to 900 • C is related to the effect of the temperature on the diffusion of aluminum in the alloy.…”
