Abstract: A tri-nickel aluminide base alloy composition is provided with a desirable combination of tensile strength and ductility. The composition is prepared to include boron dopant in combination with relatively low percentages of carbon for the high increase in strength achieved. The composition has an Ll.sub.2 of crystalline structure. It is prepared by rapid solidification at a cooling rate of at least 10.sup.3 .degree. C. per second.
