摘要

Dense nanostructured TiSi₂–SiC composite was synthesized by high-frequency-induced heated combustion synthesis method within 1 min in one step from TiC and 3Si powders. Simultaneous combustion synthesis and densification were accomplished under the combined effects of an induced current and mechanical pressure. Highly dense TiSi₂–SiC with relative density of up to 99%was produced under the simultaneous application of a 60 MPa pressure and the induced current. The mechanical properties of the composite were investigated.
