Abstract

Abstract Nanocomposite WC–8Co (mass%) powders with different CeB 6 contents were prepared using the planetary ball milling method. Effects of CeB 6 on the microstructures and mechanical properties of WC–8Co cemented carbides were investigated by X-ray diffraction, scanning electron microscope and mechanical properties testing. The results show that the grain growth and regularization of WC particles occur simultaneous with the addition of CeB 6 . CeB 6 addition improves the density and fracture toughness and decreases the volume fraction of the η (Co 3 W 3 C) phase in the materials.
