Rapid consolidation of nanocrystalline NbSi2-Si3N4 composites by pulsed current activated combustion synthesis
Tóm tắt
A dense nanostructured 4NbSi2-Si3N4 composite was synthesized by a Pulsed Current Activated Combustion Synthesis (PCACS) method within 3 minutes in one step from mechanically activated powders of NbN and Si. Simultaneous combustion synthesis and densification were accomplished under the combined effects of a pulsed current and mechanical pressure. A highly dense 4NbSi2-Si3N4 composite with a relative density of up to 98 % was produced under simultaneous application of a 60 MPa pressure and the pulsed current. The average hardness and fracture toughness values obtained were 700 kg/mm2 and 3.5 MPa·m1/2, respectively
