Simultaneous combustion synthesis and densification were accomplished under the combined effects of a pulsed current and mechanical pressure. Highly dense 2MoSi2-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 MoSi2 and SiC were about 120 nm and 90 nm, respectively. The hardness and fracture toughness values obtained were 1350 kg/㎟ and 4 MPa·m½, respectively. 한국분말야금학회 펄스 전류 활성 연소합성에 의한 나노구조의 2MoSi2-SiC 제조 및 기계적 성질 Mechanical Properties and Fabrication of Nanostructured 2MoSi2-SiCby Pulsed Current Activated Combustion Synthesis Article 2 한국분말야금학회지, v.14, no.4, pp.245 - 250 한국분말야금학회지 14 4 245 250 kci ART001076905 Pulsed current activated combustion synthesis MoSi2-SiC Composites Hardness Fracture Toughness Pulsed current activated combustion synthesis MoSi2-SiC Composites Hardness Fracture Toughness
