Solid-solution nanocrystalline powder, (Ti,V)C, was prepared via high-energy milling of Ti-Valloys with graphite. The synthesis process was investigated in terms of the phase evolution by analyzingXRD data. The rapid sintering of nanostuctured (Ti,V)C hard materials was performed by a pulsed currentactivated sintering process. This process allows quick densification to near theoretical density and inhibitsgrain growth. A dense, nanostructured (Ti,V)C hard material with a relative density of up to 100% was producedby simultaneous application of 80 MPa and a pulsed current for 2 min. The microstructure and mechanicalproperties of the resulting binderless (Ti,V)C were investigated. KCI Citation Count: 32
