Nanosized WC powder was synthesized by solid state reaction between tungsten nitride (W2N) and carbon black. The reaction path and the phase evolution during the synthesis were studied. It was found that W2N firstly decomposed to tungsten metal in the middle stage of synthesis, and then it reacted with carbon black to form W2C and WC in sequence.
Using this WC powder as the starting material, binderless WC hardmetals were prepared by hot pressing, and the microstructure and mechanical properties of the material were investigated.
