Abstract
The high-temperature consolidation of nanopowders of pure tungsten carbide by electropulse plasma sintering (spark plasma sintering) is investigated. The influence of the initial size of WC nanoparticles and their preparation modes on the density, structural parameters, and mechanical properties of tungsten carbide are investigated. Samples of high-density nanostructured tungsten carbide with high hardness (to 31 GPa) and crack resistance (5.2 MPa m1/2) are fabricated.
