<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a metal member joined, allowing the formation of a heated and sintered object of a predetermined thickness of heated and sintered metal particles between metal members, keeping the heated and sintered objects of the heated and sintered metal particles between the metal members, rigidly joining of the metal members by the heated and sintered object of metal particles, and preventing invasion and passage of liquid or gas in the sintered object, and the metal member joined body. <P>SOLUTION: A pasty metal particle composition made of (A) the heated and sintered metal particles of an average particle size (median diameter D50) of 0.01-50 μm and (B) a volatile dispersant is interposed among the plurality of metal members. By heating under pressure-free condition (1), the volatile dispersant is vaporized, and the metal particles are sintered among them. A porous sintered body is thus generated having a void content at section of 15% or more in terms of area ratio. Using the porous sintered body, the plurality of metal members are joined and then the metal members are heated (2) at a temperature higher than the above heating (1) for reducing the porous content of the porous sintered body below 15%. The metal member joined body is thus obtained. <P>COPYRIGHT: (C)2012,JPO&INPIT |
