There is provided a process for producing titanium composite, comprising the steps of: molding titanium powder, titanium alloy powder, or powder comprising titanium into a certain shape by a cold isostatic press or cold press; reacting the shape with hydrocarbon gas at its decomposition temperature or higher, to form TiC therein; and providing the shape with high density by vacuum sintering, hot isostatic pressing, hot forging, hot rolling and/or the combinations thereof. TiC a reinforcing material, is in-situ formed by reacting a cold-pressed body of the powder with hydrocarbon gas and cleaner than the externally added one and distributed more uniformly and finely in the Ti matrix, leading to a significant improvement in wear resistance and high temperature property.
