    • A heat treatment method and a connection structure in a press-fit connection of element members forming a metal element part capable of developing excellent corrosive resistance and pressure resistance. A second member is pressed into the hole of a first member with a prescribed pressure, a current is applied across these both members to generate an electrical resistance heat at a connection part therebetween, and the second member is press-fitted into the hole part so as to form a connection boundary surface in a connection surface part between the second member and the inner wall surface part of the hole part so that the press-fit connection is brought into the state of solid phase. The connection part by the press-fit connection is heated, held, and tempered to disperse and dissipate the connection part, and the metallographic structures of both members connected to each other by the press-fit connection at the connection part are integrally formed or homogenized.
    • 在形成能够显现优异的耐腐蚀性和耐压性的金属元件部件的元件构件的压入连接中的热处理方法和连接结构。 将第二构件按规定的压力按压在第一构件的孔中,跨越这两个构件施加电流,以在其间的连接部分产生电阻热,并且将第二构件压配合到孔部分中 为了在第二构件和孔部的内壁面部之间的连接面部形成连接边界面,使得压配合连接成固相状态。 通过压配合连接的连接部分被加热,保持和回火以分散和消散连接部分,并且通过连接部分处的压配合连接的两个部件的金相组织整体形成或均质化 。
