摘要： A unified junction structure which is obtained by jointing a rare-earth magnet (2) and an alloy material which is a high melting point metal or a high specific strength material by hot isostatic pressing and by solid state diffusional joining and a structure which is obtained by placing a thin layer of the high melting point material between the rare-earth magnet (2) and the alloy materials (3 and 4) which are a high specific strength material and joining the layers and materials into one body. The hot isostatic pressing is such that an object prepared by stacking the rare-earth magnet and the high melting point metal layers is put into an enclosed high pressure vessel, a predetermined pressure is applied to the object at a predetermined temperature in an inert gas atmosphere for a predetermined time and the object is pressed uniformly isostatically by the synergistic effect of pressure and temperature and jointed integrally. By this method, a junction structure which can be integrally jointed with another metal member while the brittleness and the lack of rigidity, elasticity, etc. of the rare-earth magnet are covered and magnetic characteristics are not deteriorated.
