    摘要： A method of manufacturing specialized alloys having specific properties and an alloy made using this method. The methods involve the use of micro and/or nano-sized particles that are mixed into an alloy using a friction stir welding method. The micro and/or nano-sized particles are used to alter one or more characteristics of the alloy in the locations in which the micro and/or nano-sized particles are added. The micro and/or nano-sized particles may be metal particles, non-metal particles, or a combination thereof.

    摘要： A method of welding alloys having directionally-solidified grain structure. The methods improve the weldability of these alloys by creating a localized region of fine grain structure, wherein the welding occurs in these localized regions. The localized regions are formed by applying strain energy using a variety of different methods, such as by hammer peening, laser peening or sand blasting. Then, a heat treatment step may be used to create recrystallized grains having the fine grain structure. The region of fine grain structure provides better weldability.

    摘要： A consumable insert (10) formed of material particles (14) contained within a sheath (12). The particles may be a melting point depressant that has a concentration that is greater in a center region (16) of the insert than in the surface region (18) of the insert, thereby facilitating complete melting of the insert during a transient liquid phase bonding process. Alternatively, the particles may be a low-ductility material, such as a superalloy or an MCrAlY alloy, contained within a high ductility sheath material formed into a ribbon shape, thereby allowing the low-ductility material to be delivered in ribbon form during a coating process.

    摘要： An improved method of heat treating superalloys prior to welding includes subjecting only the portion of the component to be repaired to a localized heat treatment, leaving the remainder of the component untreated. The localized heat treatment permits the use of higher hold temperatures that are near, at, or above the Ni3(Al,Ti) solution temperature of the alloy. Such heat treatment prevents strain age cracking and also prevents recrystallization in areas that are not heat treated. Such localized heat treatment can be applied before and/or after welding, for material rejuvenation, pre-brazing, and post-brazing.
