Nickel aluminide base compositions consolidated from powder

摘要

A metal body having high tensile strength and ductility at temperatures over 1000 DEG 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: (Ni1-xAlx)100-yBy 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 DEG C. and 1200 DEG C. following such machining.
