The rapid sintering of nanostructured TiC hard materials in a short time was investigated with High-Frequency Induction Heating Sintering process. 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 TiC hard material with a relative density of up to 99% was produced with simultaneous application of 80 MPa pressure and induced current of output of total power capacity (15 kW) within 4 min. The effect of the ball milling times on the sintering behavior, grain size and mechanical properties of binderless TiC was investigated.
