Dense nanostructured was synthesized by high-frequency induction-heated combustion synthesis (HFIHCS) method within 1 minute in one step from mechanically activated Nb and Si powders. Highly dense with relative density of up to 99% was simultaneously synthesized and consolidated under the combined effects of an induced current and mechanical pressure of 60 MPa. The average grain size and mechanical properties (hardness and fracture toughness) of the compound were investigated

Using the high-frequency induction heated combustion method, the simultaneous synthesis and densification of (x=0, 10, 20, 30) composites was accomplished using elemental powders of W, Si and C. A complete synthesis and densification of the materials was achieved in one step within a duration of 2 min. The relative density of the composite was up to 97% for the applied pressure of 60MPa and the induced current. The average grain size of are 6.9, 6.1, and , respectively. The hardness and the fracture toughness increases with increasing SiC content. The maximum values for the hardness and fracture toughness are .
