Ordered intermetallic compounds of iron, nickel, and titanium are materials recently under development for structural applications. Among these, Ni/sub 3/Al has been made reasonably ductile by the addition of small amounts of boron. Further additions of zirconium and chromium have been utilized for enhancement of high temperature strength and intermediate temperature ductility. Nickel aluminide alloys based on Ni/sub 3/Al are near commercialization. This paper describes the melting, processing, mechanical properties, physical properties, corrosion, and weldability of these alloys. Applications for nickel aluminides have been identified. Potential suppliers who have recently licensed the nickel aluminide technology from Oak Ridge National Laboratory (ORNL) are also listed. 16 refs., 7 figs., 7 tabs.
