Nickel aluminide base compositions consolidated from powder.

摘要

A metal body having high tensile strength and ductility at temperatures over 1000°F is provided. The body is prepared by hot isostatic pressing of powder formed by atomization of a melt of an alloy. The alloy composition base is according to the formula:
(Ni<Sub>1-x</Sub>Al<Sub>x</Sub>)<Sub>100-y</Sub>B<Sub>y</Sub>
where x is between 0.23 and 0.25, and
where y is 0.1 to 2.0.

The consolidated body is suitable for machining and may be annealed for a couple of hours at temperatures between 800°C and 1200°C following such machining.
