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:(Ni1-xAlx)100-yBywhere x is between 0.23 and 0.25, andwhere 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.
