Title: Advances in processing techniques for nickel aluminides

Abstract

The status of processing technology at ORNL for three nickel aluminide alloys is presented in the form of flow charts. The technologies discussed include powder processing, melting techniques, near-net-shape processes from molten metal, and cold and hot working of cast products. Tensile properties are compared for one of the three alloys after six different processing techniques. Creep-rupture strength is compared for the three nickel aluminide alloys in the cast and wrought condition. Grain size was the main difference between the material produced by various processing techniques. Significant advances in processing technology of nickel aluminides could find them in use for a range of applications in the future. 7 refs., 9 figs., 2 tabs.
