COBALT-BASED SUPERALLOYS WITH STABLE GAMMA-PRIME PRECIPITATES, METHOD OF PRODUCING SAME

摘要

A cobalt based superalloy and a method of producing the same. The superalloy includes a nominal composition comprising at least cobalt, aluminum, Z and vanadium, Z being at least one of tantalum and niobium, processed such that the superalloy comprises gamma and gamma-prime phases with stable gamma+gamma-prime microstructures.
