Nickel Aluminium Zirconium Alloys
Abstract: The present subject matter describes Ni-Al-Zr alloys which include Ni as the major component with the additions of 9-20% Al and 4-14% Zr by atomic percentage. In one embodiment the present subject matter describes a group of alloy compositions in a Nickel- Aluminium- Zirconium (Ni-Al-Zr) system corresponding to a concentration range of about 9-20 % Al and about 4-14 % Zr by atomic percentages and the balance being Ni. In other embodiment the present subject matter includes at least one eutectic constituent including at least two of the intermetallic compounds or phases Ni3Al NiAl Ni5Zr Ni7Zr2 and derivatives that are realized within the aforementioned composition group.
