>A statistically designed experiment consisting of nine melts was carried out to determine the main effects of Zr, Nb, and Mo in a base alloy of Fe- -Al and Cr. Additions of Zr, Nb, and Mo increases the stress rupture life of the base alloys. Zirconium had a deleterious effect on oxidation resistance of the base alloy samples tested at 1650 and 1800 deg F and Nb had a beneficial effect at 1800 deg F. Zirconium improves the high temperature yield strength of the base alloy. The room temperature ductility of the base alloy decreases with increasing additions of Zr and Nb. (W.L.H.)
