摘要： PURPOSE:To enable strongly the joining of both joining members by existing super plastic alloy on the part where two joining members to be subjected to solid phase bonding are opposing and by applying a big plastic deformation on the part opposing to the joining face of this super plastic alloy. CONSTITUTION:Two joining members 1A, 1B are inserted into the die 2 having taper part 2a on the way, opposing each other on the taper part 2a the joining face 3 to be joined and supporting the rear part by pistons 4, 5 respectively. The interface of the joined face 3 performs plastic deformation with enlarging the area when a load is applied in the direction to compress the joining member 1A, 1B by piston 4 and a new face is caused on the interface. The joining members 1A, 1B return to the original shape once again when it is unloaded by returning the piston 4 to the original position. Further new face is caused with shrinking the interface at this returning time. The crystal grain having high activity appears on the joining interface by repeating such operations and two joining members 1A, 1B are strongly joined.
