摘要： A coated article has a metallic substrate with a substrate composition, and a metallic coating overlying and contacting the metallic substrate. The metallic coating has a metallic-coating composition different from the substrate composition. A protective coating overlies and contacts the metallic coating. The protective coating includes an aluminide layer overlying and contacting the metallic coating, and optionally a thermal barrier coating overlying and contacting the aluminide layer. This structure may be used to restore a key dimension of an article that has previously been in service and to protect the article as well.

摘要： Gamma titanium aluminide intermetallic compositions (gamma TiAl intermetallics) based on the TiAl (gamma) intermetallic compound. The gamma TiAl intermetallics contain chromium and niobium, as well as controlled amounts of carbon that achieve a desirable balance in room temperature mechanical properties and high temperature creep capabilities at temperatures approaching and possibly exceeding 1600° F. (about 870° C.).

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.

摘要： Methods of processing compositions containing titanium and aluminum, especially titanium aluminide intermetallic compositions (TiAl intermetallics) based on the TiAl (gamma) intermetallic compound. The methods entail processing steps that include a hot isostatic pressing (HIP) cycle and a heat treatment cycle that can be performed in a single vessel. TiAl intermetallic compositions processed in this manner preferably exhibit a duplex microstructure containing equiaxed and lamellar morphologies.
