The sum of atomic percent aluminum and atomic percent titanium is from about 2 to about 6 percent, the ratio of atomic percent aluminum to atomic percent titanium is at least about 1.5, and the atomic percent of aluminum plus titanium divided by the atomic percent of niobium equals about 0.8 to about 1.3. The nickel-base alloy may be provided in the form of an article of manufacture, such as, for example, a disk, a blade, a fastener, a case, or a shaft. A method for making a nickel-base alloy also is disclosed. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

    Abstract: The present invention is directed to alloy ingots and other alloy workpieces, and to methods for processing alloy ingots and other alloy workpieces. Ingots and other workpieces composed of crack sensitive alloys may form cracks along their surfaces and/or edges during hot working operations which may increase production time and expense, and reduce yield. The method of the present invention provides a more efficient and/or cost-effective method of hot working crack sensitive alloys. Specifically, in one embodiment the invention provides a method of processing an alloy workpiece to reduce thermal cracking, the method comprising spraying a metallic coating material onto at least a portion of a surface of the alloy workpiece to form a surface coating metallurgically bonded to the alloy workpiece; wherein the surface coating is more ductile than the alloy workpiece; and wherein the surface coating reduces heat loss from the alloy workpiece. In another embodiment, the invention also provides a method of processing an alloy workpiece to reduce thermal cracking, the method comprising: inserting the alloy workpiece into a metallic canister, wherein the metallic canister has a lower coefficient of thermal expansion than the alloy workpiece and includes an inner surface comprising a nickel-boron coating on at least a portion of the inner surface; encapsulating the alloy workpiece in the metallic canister to provide a canned assembly; removing at least a portion of gas from the interior of the canned assembly; and heating the canned assembly to transient liquid phase bond the alloy workpiece to the metallic canister; wherein the metallic canister reduces heat loss from the alloy workpiece.
