ABSTRACT:
Target members of titanium or a titanium alloy with melting point M are bonded together by first forming a bonding layer with melting point J lower than M on at least one of the bonding surfaces over which the target members are to be joined together. While the target members are pressed against each other over the bonding surfaces, end parts of the target members adjacent the bonding surfaces are heated to an intermediate temperature T such that J<T<M and is kept at this intermediate temperature for a specified length of time to effect liquid-phase diffusion bonding. Alternatively, an insert member of titanium or a titanium alloy may be inserted between the bounding surfaces of the target members to form liquid-phase diffusion bonding by first forming bonding layers of the type described above on mutually opposite end surfaces of the insert member and then inserting the insert member between the target members.
