PROBLEM TO BE SOLVED: To provide a new insert material capable of obtaining sound joined boundaries at the time of joining a Ti-Al series intermetallic compd. and a Ti base alloy and free from the generation of cracking in the Ti-Al series intermetallic compd. SOLUTION: This joined body is the one in which both side faces are provided with brazing filler metal layers 12 and 14 via a stress relaxing layer 13, and three forms are shown. Concretely, as a primary insert material, the brazing filler metal layers 12 and 14 are formed by Al alloy solder, and the stress relaxing layer 13 is formed by Ag or an Ag alloy. As a secondary insert material, the brazing filler metal layers 12 and 14 are formed by Ag-Cu series solder contg. In, and the stress relaxing layer 13 is formed by Cu or a Cu alloy. Then, as a third insert material, the bazing fillet metal materials 12 and 14 are formed by Ag-Cu series solder contg. In, and the stress relaxing layer 13 is formed by Ag or an Ag alloy. |
