ABSTRACT:
A beta phase nickel aluminide microalloyed with gallium having improved ductility. Nickel aluminide intermetallics alloyed with up to about 0.25 atomic percent gallium have significantly improved room temperature ductility over conventional unalloyed beta phase nickel aluminides or beta phase nickel aluminides alloyed with higher percentages of gallium.
