Abstract
Dense nanostructured 2MoSi_2-SiC composites were synthesized by the pulsed current activated combustion synthesis (PCACS) method within 3 minutes in one step from mechanically activated powders of Mo_2C and 5Si. Simultaneous combustion synthesis and densification were accomplished under the combined effects of a pulsed current and mechanical pressure. Highly dense 2MoSi_2-SiC with relative density of up to 96% was produced under simultaneous application of a 60 MPa pressure and the pulsed current. The average grain size of MoSi_2 and SiC were about 120 nm and 90 nm, respectively. The hardness and fracture toughness values obtained were 1350 kg/mm2 and 4 MPacdotm1/2, respectively.
