Abstract
A modified class of nickel aluminide (NiAl) type material is disclosed having useful amounts of toughness and ductility at low temperatures, e.g. room temperature. The basic NiAl material is modified with an additional of the material such as cobalt which produces a structure which is susceptible to undergoing a martensitic transformation. The martensitic structure when produced results in a significant increase in toughness and ductility at low temperatures.
