Abstract

A beta phase nickel aluminide microalloyed with iron having improved ductility. Nickel aluminide intermetallics alloyed with no more than about 0.5 atomic percent iron have significantly improved room temperature ductility over conventional unalloyed beta phase nickel aluminides or beta phase nickel aluminides alloyed with higher percentages of iron.
