AbstractThe SiC/FexSiy composites were synthesized by reaction sintering process with iron tailings as raw material and carbon as reductant. The room and high temperature flexural strengths and fracture toughness of composites were studied in this paper. Fracture surfaces were observed by means of a scanning electron microscope (SEM). The results showed that the room temperature flexural strength of SiC/FexSiy composites changed along with the different contents of FexSiy and sintering temperature. The flexural strength of composites reaches the maximum at 900 C. The correlation between flexural strength and temperature is consistent with curve I. The fracture toughness of composites is related to the content of FexSiy. The fracture behavior of composites is mainly transcrystal line in room temperature and intercrystalline in high temperature.
