| Abstract: | The five ultrafine WC-Co rare cemented carbides powders doped different TaC content were prepared by 72 hours high-energy ball milling.The powder was cold isostatic pressed and vacuum sintered at 1 380 ℃.Effect of the content of TaC on the physical properties and the micrographs of the alloys was discussed with emphasis.The results show that addition of TaC was conducive to the physical properties of the alloys and the TaC could inhibit the grain growth. |
