Method of forming strong fatigue crack resistant nickel base superalloy and product formed.

摘要

A novel alloy is provided having approximately the following ingredient formula: <IMAGE> The alloy has a low solvus temperature for the gamma ' precipitate thus facilitating metal processing and treatment and also forging of the metal. Fatigue crack propagation rate is remarkably low for metal samples cooled at rates of 20 DEG C/min to 200 DEG C/min.
