A single phase of NaCl-type structure of Ti_<44>C_<56> alloy powder has been synthesized by ball-milling elemental Ti and graphite powders at room temperature. The end-product of Ti_<44>C_<56> that is obtained after 720 ks of milling consists of fine grains of about 3 nm in diameter and possesses homogeneous powder with an average particle diameter of less than 0.4μm. The milled powder has been consolidated into bulk samples, using a plasma activated sintering method. This consolidation step leads to the formation of fully-dense TiC compacts with nano-structure grains. The as-milled powder and the as-consolidated bulk samples have been characterized after selected milling times by means of X-ray diffraction, transmission electron microscope, scanning electron microscope and chemical analyses. Some of the compacted samples were investigated by small-angle X-ray scattering and high-resolution transmission electron microscope. The hardness and some mechanical properties of the end-product are reported. On the basis of the results of the present study, the ball-milling technique accompanied with plasma activated sintering can provide powerful tools for fabrication of nanocrystalline TiC bulk alloys.mechanical alloyingtitanium carbideconsolidationnanocrystalline materialsstructuremorphology
