Effect of Forming Process on Sintering Density and Microstructure Defects of WC-6Ni Fine Grained Cemented Carbides AITranslate
Abstract AITranslate
The forming processes of molding, cold isostatic pressing and molding ＋ cold isostatic pressing were adopted for the preparation of WC-6Ni cemented carbides. The effects of different forming processes on the phase composition,physical properties and microstructure of WC-6Ni cemented carbides were main- ly discussed. The results show that the WC-6Ni fine grained cemented carbide with density of 98 % arid HV hardness of 1 457 can be obtained by sintering at 1 410 ℃ for 1 h of the WC-6Ni compact from molding ＋ cold isostatic pressing. The above cemented carbide has uniformly distributed microstructure,and there are no voids and defects such as Ni pools on its surface.
