摘要： Its basic means is a monolithically bonded construct prepared by monolithically bonding together a rare-earth magnet 2 and a an alloy material that is a high melting point metal or a high specific-tenacity material through the solid phase diffusion bonding by the hot isostatic pressing treatment, and a monolithically bonded construct with an interposal of a thin layer of the high melting point metal between a rare-earth magnet 2 and an alloy material 3, 4 that is a high specific-tenacity material. As a method for the bonding, there is used a hot isostatic pressing treatment method in which a rare-earth An magnet and a high melting-point metal are laminated together, thereby to prepare an object to be treated, then the object is put into a hermetic-type high pressure container having an inner wall portion equipped with a heater, then the object is uniformly pressurized in all directions by a synergistic effect caused by pressure and temperature, while the object is maintained for a certain period of time under a certain pressure and temperature condition in an atmosphere of an inert gas, thereby to monolithically bond the object. With this, it is possible to obtain a bonded construct in which a magnet can monolithically be bonded with another metal member with a high strength, without deteriorating magnetic characteristics, such that the rare-earth magnet's insufficiency in brittleness, rigidity, tenacity and the like is compensated.
