摘要： A repair method that includes covering a damaged part of a member to be repaired with a repair material, and heating the repair material to a predetermined temperature to form an alloy layer. At least the surface of the member to be repaired is a first metal such as Cu. The repair material includes a second metal such as Sn. By the heating, the surface of the member to be repaired is integrally joined with a layer of an intermetallic compound and an alloy having a melting point higher than a melting point of either of the first metal or the second metal.

摘要： A first structural material is bonded to a second structural material with a joining material provided with a mixed layer of a raw-material component for forming an intermetallic compound layer and a resin component that softens and flows during heat treatment interposed therebetween to form bonded structural materials. When the bonded structural materials are heat-treated, the first structural material is joined to the second structural material with an intermetallic compound layer, and the resin component exudes and covers the lateral circumferential (exposed) portion of the intermetallic compound layer with a resin film.
