Abstract
The oxidation behaviour of three industrial Fe-Cr-Al alloys was studie d. Two of the products examined were Fe-Cr-Al alloys, one being fabric ated by powder metallurgy while the third one was a Fe-Cr-Al-Y alloy. In particular, we have shown that, at high temperature, yttrium may ha ve a detrimental effect on the hot oxidation resistance of this type o f alloy. Powder metallurgy does not seem to improve the high temperatu re behaviour of Fe-Cr-Al alloys as stated by the manufacturer.
