Consolidation and mechanical properties of nanostructured MoSi2–SiC–Si3N4 from mechanically activated powder by high frequency induction heated sintering

A dense nanostructured MoSi2–SiC–Si3N4 composite was sintered by the high frequency induction heating method within 2 min from mechanically activated powder of Mo2N, Mo2C and Si. Highly dense MoSi2–SiC–Si3N4 composite was produced under simultaneous application of a 80 MPa pressure and the induced current. Mechanical properties and grain size of the composite were investigated. The average hardness and fracture toughness values obtained were 1420 kg/mm2 and 4.5 MPa m1/2, respectively.
