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： A welding filler metal is manufactured by casting a nickel-base alloy as an extrusion rod having a diameter of from about 0.2 inch to about 0.5 inch. The extrusion rod has at least about 12 grains in the cross section of the extrusion rod. The extrusion rod is extruded in a single extrusion operation to a filler-metal diameter of less than about 0.1 inch and using an areal extrusion ratio of at least about 9:1 to form the welding filler metal. Preferably, the process is used to make a nickel-base superalloy welding filler metal of a diameter of about 0.05-0.06 inch from an extrusion-rod casting of about ¼ inch diameter and having at least about 12 grains in the cross section.
