tungsten-carbide die at a pressure of 1 GPa for 24 h. This compact is then subjected
to hot compaction for 30 min at temperatures in the vicinity of 400°C and pressure
up to 870 MPa. The final density of the compact is 99.2% of the maximum possible
density. Figure 6.2 presents the distribution of grain sizes in the material showing
that it consists of nanoparticles ranging in size from 20 to 70nm, with the largest
