Abstract:	Electroslag remelted cast iron-aluminum alloys having the compositions: 1) Fe-16Al-0.5C, 2) Fe-10Al0.5C, and 3) Fe-8Al-0.5C were employed to investigate the effect of Al on the oxidation behavior of Fe-0.5C alloys in the temperature range 973 - 1273 K. Microstructural and phase analyses of these alloys revealed distribution of a carbide phase, Fe3AlC0.692 in the Fe3Al matrix of alloy I and in Fe-Al matrix of alloys 2 and 3. The oxidation behavior of these alloys was found to be dependent upon relative composition and stability of the carbide and matrix phases. High-Al content alloys were free from decarburization, whereas low-Al content alloys suffered from decarburization.
