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.

摘要翻译：要解决的问题为了解决不能确保接合部分的健全性的问题，在钎焊中的不同种类的材料之间的接合面中形成脆性低强度金属间化合物所引起的问题或焊接方法，但是例如在ITER装置（核聚变反应堆）的超导线圈护套中需要将外套材料焊接到不同种类的材料上。
解决方案：由纯Ti /铜合金（插入材料）/低温不锈钢构成的不同种类的材料直接叠加，然后通过高温各向同性加压（HIP）进行加工，从而不形成反应层例如接触区域中的金属间化合物。版权所有（C）2005，JPO＆NCIPI
