| Abstract: | The progress of the synthesis methods of nano size WC Co powder including Mechanical Alloying, Spraying Conversion Process, in Situ Carbonization Reduction, coprecipitation etc.,were introduced. The densification temperature was decreased obviously and the grain growth was serious in the sintering period of the nano size WC Co powder. The microstructures and the mechanical properties of sintered hardmetal were reviewed. The problems needed to be solved is the control of gains growth when sintering and the future direction on the development of the nanostructured cemented carbide is adopting new sintering methods to realize the rapid sintering. |
