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










Image Number 9 for United States Patent #4888064.

A novel alloy is provided having approximately the following ingredient formula: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.degree. C./min to 200.degree. C./min.
