Abstract
A precipitation hardenable, cobalt-nickel base superalloy is disclosed. The is characterized by the following weight percent composition. The balance of the alloy is cobalt and usual impurities. The alloy provides a novel combination of strength and ductility after long-term exposure to elevated operating temperatures as found in gas turbines and jet engines. A fine-grain steel article made from the alloy is also disclosed. The steel article is also characterized by a continuous surface layer of AlOand CrOthat protects the alloy from oxidation at the elevated operating temperatures.
