Abstract
Nanopowders of MoSi2 and Si3N4 were synthesized from Mo2N and Si by high ball milling. Dense nanostructured 8MoSi(2)-Si3N4 composite was consolidated by high frequency induction heated sintering (HFIHS) method within two minutes from mechanically synthesized powders of MoSi2 and Si3N4. Highly dense 8MoSi(2)-Si3N4 composite with a relative density of up to 97 % was produced under simultaneous application of 80 MPa pressure and the induced current. The average grain size and mechanical properties (hardness and fracture toughness) of the composite were investigated.
