Nickel-based alloys can be classified into those tht form chromia or alumina as protective scale on oxidation. Alumina-forming Ni-based alloys exhibit better high temperature oxidation resistance and possess sufficient strength and creep resistance properties. Aluminum present in the alloy forms gamma prime (Ni 3 Al) precipitates that impart high strength to these alloys.
