Abstract
Oxide-dispersed Fe-28at.% Al-2%Cr alloys were produced by a powder metallurgy technique followed by hot extrusion. Yttria and ceria were added to the base alloy to assess the effect of these dopants on the oxidation behavior. The amount of dopant was varied from 0.05-0.5 at.% Y in a series of Y2O3-dispersed alloys. Isothermal and cyclic oxidation testing was conducted at temperatures from 800° to 1300°C. A CeO2 addition was detrimental to the oxidation behavior. The Y2O3 improved the α-Al2O3 scale adhesion relative to an undoped alloy, but was not as effective as similar additions to an oxide-dispersed FeCrAl alloy.
