Abstract

High-temperture oxidation behavior of Fe-20Cr-10Al fibers and disks with small amounts of reactive elements was studied at 1473K for 18.0ks in oxygen. Mass gain of these fibers increased in the order of Fe-20Cr-10Al-0.05Ti-0.05Hf<Fe-20Cr-10Al-0.05Ti-0.1Y<Fe-20Cr-10Al-0.05Ti-0.01Hf<Fe-20Cr-10Al<Fe-20Cr-10Al-0.05Ti-0.05Y<Fe-20Cr-10Al-0.05Ti. This result suggested that the addition of small amounts of reactive elements to the these fibers decreased the rate of oxidation.
