OSTI ID:4048172

The preparation and properties of aluminum-ironniobium alloys are described. The alloys exhibit unusual strength and oxidation resistance under extreme hightemperature service conditions.. The niobium-base alloys consist essentially of at least 55% by weight of niobium, 1 to 20% aluminum, and 1 to 20% iron, and optionally containing 0 to 35% cobalt, nickel, tungsten, and zirconium, 0 to 5% of one or more of beryllium, manganese, molybdenum, silicon, thorium, and vanadium, the total of this group not to exceed 15%, and 0 to 2% of one or more of boron, carbon, calcium, and cerium, the total of this group not to exceed 5%, and the normal impurities.
