摘要：

Iron aluminides are known for their excellent oxidation and corrosion resistance. If they are exposed to hostile environment, a protective Al2O3 layer creates on its surface. Through an addition of Zr, their high temperature mechanical properties could be enhanced, however, their oxidation resistance is also affected. A small amount of Zr enhances the high temperature oxidation resistance, but at higher concentration it creates ZrO2 which has a detrimental effect on the oxidation behaviour.
