Abstract
The oxidation behavior of Fe–6Al with different Cr contents (0–24 at.%) at 650 °C in air was investigated so as to clarify the role of Cr in the oxidation resistance of the Al-rich amorphous oxide layer. The time to breakdown of the Al-rich amorphous layer was found to increase with increasing alloy Cr content. This corresponds to the time to increase the rate of oxidation by formation of Fe3O4. Such a beneficial effect of Cr to maintain the protective Al-rich amorphous layer for a longer oxidation time is attributed to the enhancement of outward diffusion flux of Al by positive “cross-term effect” of Cr in the Al- and Cr-depleted zone.
