    摘要： A heat treatment process that will restore the mechanical properties of an aircraft engine article that includes a cast nickel-based superalloy portion welded to a wrought portion. The heat treatment process includes placing an article that includes the nickel-based superalloy cast portion into a heat treatment chamber, evacuating the chamber to a suitable atmosphere, heating the chamber in a manner that minimizes distortion of the cast portion to a temperature in the range of 1950° F. to 2050° F., holding the temperature in that range for a period of time sufficient to solution all the delta phase precipitates, and then cooling the article to room temperature in a manner that minimizes distortion of the article. After solution heat treatment, the wrought portion of the engine part can be removed and replaced and the engine article can be reprocessed.

    摘要： Nickel-base alloys suitable for use as a weld material to weld high-temperature components (10), such as turbine blades and vanes of gas turbine engines. The nickel-base alloys consist essentially of, by weight, 5 to 10 percent chromium, 3 to 14 percent cobalt, up to 4 percent molybdenum, 3 to 7 percent tungsten, 5 to 9 percent tantalum, 5 to 8 percent aluminum, 0.1 to 2 percent hafnium, 0.005 to 0.03 percent boron, up to 0.15 percent carbon, the balance being nickel and incidental impurities and/or residual elements. Welds (12) formed with the alloys are capable of exhibiting desirable levels of strength and oxidation resistance, while containing little if any rhenium.
