Abstract
High-speed consolidation of pure tungsten carbide powders by electropulse plasma sintering («Spark Plasma Sintering») has been carried out. The effect of initial WC nanoparticle size and their production conditions on density, structural parameters, and mechanical properties of tungsten car- bide has been studied. Samples of high-density nano-structural tungsten carbide with high hardness (up to 31 GPa) and crack growth resistance (5,2 MPa ∙ m1/2) are obtained.
