摘要：
In the present paper, the combustion synthesis processes of the system of Fe based composites, mainly containing Fe-Ti-C, under an electric field was studied by using a Gleeble 1500D thermal simulation instrument. The results showed that there was a great change in temperature inside the sample under rather low temperature, compared with that in the self-propagating high temperature synthesis (SHS) processes. This indicated that a reaction may occur, which led to a great deal of heat release. Analyses by X-ray diffraction proved that the microstructures of the sample after combustion consist of TiC, alpha-Fe and a little Fe2Ti. Therefore, it was demonstrated that Fe/TiC system can be synthesised in an electric field, even under low temperature.
