High-temperature oxidation of Fe-20Cr-4Al alloy purified by floating zone melting was studied for 360ks in air at 1373, 1473, 1573 and 1673K. Oxide adherence of the alloys purified by froating zone melting was improved. Mass changes of 0.99, 1.23, 1.84 and 3.88ppmS alloys increased with increasing temperature of oxidation. Mass change of 3.88ppmS alloy showed the smallest values at any temperatures of oxidation because of spalling of oxide scales on the alloy.
