Abstract: The in-situ synthesis of 10 vol% (TiW)C-Fe composite was investigated by melting the Fe-W, Fe-Ti and Fe-C alloys with melting temperature and time controlled. The microstructure and phase composition were checked by employing SEM and XRD with Cu Kα radiation. The results showed that (Ti,W)C particles, as the only ones, can form reinforcement when the alloy is melted at higher temperature and/or longer time by properly controlling solidification rate. (Ti,W)C particles are evenly distributed in the matrix due to the lower mismatched densities between (Ti,W)C particles and liquid metal.
