Abstract
The oxidation behavior of Fe-15Cu-10Al alloy was investigated at 700°C. Oxidation kinetics of the alloy conformed nearly to the parabolic rate law. The scales were composed mainly of alumina, plus a few nodules rich in iron. The very low oxidation rate of Fe-15Cu-10Al alloy showed that 10at.% Al level reached the critical Al content to form a complete Al2O3external layer. Compared with the corresponding Fe-10Al binary alloy, the addition of 15at.% Cu played a beneficial role for the establishment of the full protective alumina layer.
