The mechanical alloying process has been employed successfully for preparing nanocrystalline titanium carbide (TiC) alloy powders. This process was performed in a high-energy ball mill under an argon atmosphere at room temperature. The mechanically reacted powders have been characterized as a function of the milling time by means of X-ray diffraction, scanning electron microscopy and transmission electron microscopy. A single phase of NaCl-type Ti44C56 alloy powders is formed after very short milling time (20 ks). The end product of the milled powders are uniform in size (less than 0.5 μm in diameter) and homogeneous in shape (almost spherical). Moreover, the fabricated Ti44C56 alloy powders have extremely fine cell-like structure, being of about of 3 nm. The presence of free Ti -nd/or C (reactant materials) in the end product could not be detected. These results demonstrate that the mechanical alloying process can provide a powerful tool for the fabrication of TiC alloy powders at room temperature.
