Abstract

(W,Ti)C and Si nanopowders were obtained using high-energy ball milling. A dense, nanostructured (W,Ti)Si₂-SiC composite was synthesized by a one-step, high-frequency induction heated combustion synthesis method within 2 min from mechanically activated powders of (W,Ti)C and 3Si. Simultaneous combustion synthesis and consolidation were accomplished under the combined effects of an induced current and mechanical pressure. The average grain size and mechanical properties of the composite were investigated.
