Abstract

High-temperature oxidation of Fe-20Cr-4Al alloy purified by floating zone melting was studied for 18.0ks in oxygen at 1273, 1373, 1473, 1573 and 1673K. Mass changes of 0.99ppmS and 1.84ppmS alloys increased with increasing temperature of oxidation. On the other hand, mass change of 3.88ppmS alloy showed negative values after oxidation at 1473, 1573 and 1673K, because of spalling of oxide on the alloy.
