Melting, casting, and processing of nickel and iron aluminides
- Oak Ridge National Lab., TN (United States)
The nickel and iron-aluminide alloys are an important class of materials because of their unique resistance to oxidizing, carburizing, and sulfidizing environments at high temperatures. They also provide an interesting combination of high-temperature strength and wear resistance. Many applications have been identified for these materials including: furnace fixtures, heating elements, pumps, hydroturbines, and forging and extrusion dies. Because of the large aluminum content of the aluminides, most conventional material vendors are reluctant to melt large-size heats of these materials. The purpose of this paper is to describe a newly developed furnace loading scheme that permits commercial melting of nickel and iron aluminides. Along with melting, the paper also provides data regarding the casting and processing of Ni{sub 3}Al- and Fe{sub 3}Al-base materials. Examples of commercial successes with component manufacturing of nickel and iron aluminides are also discussed.
