Abstract  The critical Al content for the selective formation of alumina scales on Fe-Al alloys has been analyzed by investigating the oxidation behavior of binary Fe-10Al and ternary Fe-5Cr-10Al and Fe-10Cr-10Al alloys (atomic fraction, %). A possible interpretation of the effect of the third-element Cr in Fe-xCr-10Al on promoting Al2O3 scale formation not involving a transition from the internal to external oxidation of Al is briefly presented.
Key words:  Fe-xCr-10Al      mixed external scale      selective oxidation
