Ultrafine titanium carbonitride particles (TiC0.5N0.5) 100 nm in mean size were successfully synthesized by a nitridation treatment at ordinary temperatures, 1273-1373 K of nanostructured half-stoichiometric titanium carbide (TiC0.5) particles, which were produced by the magnesium reduction of gaseous TiCl4 + 1/4C2Cl4. We prepared in the next step two sintered cermets with a basic composition of TiC0.5N0..5+Mo2C + Ni using developed and commercialized TiCN powders(1-2 μm). The ball-milled powders were sintered at different temperatures using a vacuum sintering method as well and the mechanical properties were compared.
