TiC/Fe composites were successfully fabricated in situ by self-propagating high temperature synthesis (SHS) technology. The effect of Fe content on the microstructure of the synthetic products was discussed. Results showed that the SHS products of Ti-C-30wt%Fe system were mainly composed of TiC and Fe as well as a few Fe2Ti.Spherical TiC particles with 2-3μm distributed on the Fe matrix uniformly. With the increase of Fe content, the combustion temperature reduced, resulting in the decrease of growth rate of TiC particles.
