Abstract
A nickel-base cast alloy for use in high-temperature forging dies operable in the atmosphere, consisting essentially of 4-10 weight % of Al, 13-23 weight % of Mo and the balance of Ni and impurities. The nickel-base cast alloy may further contain up to 0.1 weight % of at least one of rare earth metals and Y. It may also contain up to 15 weight % of W and/or Ta substituting for a part of Mo. Ni may be replaced by up to 20 weight % of Co. The cast alloy of the present invention has high resistance to compression deformation and oxidation.
