The grain size of (W,Ti)C powder remarkably decreases with a high-energy ball milling. The rapid sintering of nanostructured (W,Ti)C and (W,Ti)C-5 vol.%CNT hard materials was investigated with high frequency induction heating. The advantage of this process is that it allows very quick densification to near theoretical density and prohibition of grain growth in nanostructured materials. A dense nanostructured (W,Ti)C and (W,Ti)C-5 vol.%CNT hard material with a relative density of up to 99% was produced with simultaneous application of 80MPa pressure and induced output current with total power capacity of 15 kW within 3 minutes. The effect of CNT on the sintering behavior and mechanical properties of (W,Ti)C was investigated. The fracture toughness of (W,Ti)C increased by addition of CNT.
