Popis: Nanocrystalline cemented carbide powder of WCCo was directly synthesized by mechanical alloying. The structure evolution of the powders was monitored by X-ray diffraction, scanning electron microscope and thermal analysis. Results show that the formation of the compounds is controlled by an inter-diffusion reaction between elements. Powders of WCCo milled for 100 h were compacted and sintered to a cylinder with the size O 6 mm×8 mm. The hardness and sintered density were measured.
