In situ synthesis of Fe-TiC composites was investigated firstly using Gleeble thermal simulation apparatus under the great thermal flux in the Fe-Ti-C system. A series of studying was taken,such as the temperature feature of compact in the process of heating, the thermodynamic calculation,the analysis of the final product by X-ray diffraction (XRD), scanning electron microscope (SEM) and energy dispersion spectrometry (EDS). The results show that the starting temperature of synthesis reaction can be decreased greatly. In this study, the synthesis react can take place at a temperature as low as 394℃ in Fe-Ti-C system Besides the litter Particles TiC in Fe-binder phase, there is a little Fe2Ti in the final products. The study provides a new route for producing Fe-TiC composites at low temperature.
