In order to synthesize composite materials free of residual silicon phase, we have investigated reaction forming of SiC/FeSix by the infiltration of SiC/C/Fe performs using silicon melts. Experiment' s result show that dense SiC/FeSix materials free of residual silicon can be obtained. Room temperature strength of this material is 220 ?Mpa. A model on the relationship between ferrous concentration and the components of second phrase is proposed. The effect of heat - treatment on the sinters is discussed.
