The maximum tensile strength of the joints is 168 MPa , and a firm joint is obtained. The microstructure of diffusion bonded joint has been observed by SEM, X ray and EPMA, and the main factors affecting diffusion bonding have been analyzed. The intermetallic compounds Ti 2Cu and TiCu were formed near the interface. The width and quantity of the intermetallic compound increases with the increase of the bonding time. The formation of the intermetallic compounds results in embrittlement of the joint and the poor joint properties.展开更多
