DIE FOR FORMING SINTER BONDED BODY, MANUFACTURE OF SINTER BONDED BODY, AND SINTER BONDED BODY

摘要

PROBLEM TO BE SOLVED: To provide a forming die capable of manufacturing a sinter bonded body formed by means of bonding in a direction intersecting a pressurizing direction at the time of sintering by a simple method, to provide the method for manufacturing the sinter bonded body by using the forming die, and to provide the sinter bonded body manufactured by the method. SOLUTION: This die for forming sinter bonded body has a cylindrical outer die 2 having a hollow part 21 capable of containing a sintering material constituting a sinter bonded body and a couple of pressers 3a, 3b for pressing the sintering material and is used for sintering the sintering material by electric discharge plasma sintering and forming a sinter bonded body constituted by bonding plural sintered compacts different from each other in density. Further, at least either of the pressers is constituted of plural pressing members dividing the pressing surface of the presser. It is preferable that the presser is constituted of an annular pressing member 31 and a columnar pressing member 32 capable of slidably fitting in a hollow part 310 of the member 31.
