摘要： PROBLEM TO BE SOLVED: To solve the problem of inability to secure soundness in a joined part, a problem caused by formation of a brittle and low-strength inter-metallic compound in a joined surface between different kinds of materials in a brazing or welding method, although welding of a jacket material to a different kind of material is required for example in a superconducting coil jacket in an ITER device (nuclear fusion reactor).
SOLUTION: Different kinds of materials composed of pure Ti/copper alloy (inserting material)/cryogenic stainless steel are directly superimposed and then processed by high temperature isotropic pressurization (HIP), so that nonfused joining is performed without forming a reaction layer such as an inter-metallic compound in the contact area.

摘要： PROBLEM TO BE SOLVED: To solve such a problem that a superconducting wire cannot demonstrate its inherent performance because a critical current significantly lowers when only a slight strain is given in an A15 superconducting wire used in a nuclear fusion reactor or the like. SOLUTION: This method is used to improve the critical current of the superconducting coil. A bending strain is given to a superconductor to release deformation on the inner-diameter side of the coil in a high magnetic field part, thereby reducing the fall of the critical current on the inner-diameter side of the coil due to thermal deformation caused by a difference in temperature between the generation temperature of the superconductor and the operation temperature of the superconducting coil.
