Title: Processing of nickel aluminides and their industrial applications

Abstract

Ductile Ni{sub 3}Al-based alloys offer unique properties. However, their use has been limited because information is lacking regarding their processing into various product forms. This paper describes the recent progress made toward melting, electroslag remelting, and the processing of large-scale ingots of one of the Ni{sub 3}Al-based alloys. Microstructural data are presented after various homogenization treatments. Both as-cast and homogenized samples were subjected to hot-compression testing. The hot-compression data for the commercial-size ingot showed the same behavior as previously reported on the experimental heats. The status of industrial applications of nickel-aluminide alloys is also described. 12 refs., 12 figs., 2 tabs.
