Title
The Effect of Rapid Consolidation of Nanostructured MoSi2-SiC Composite on its Mechanical Properties
고인용 In Yong Ko , 채승명 Seung Myoung Chae , 손인진 In In Shon
Abstract
A dense nanostructured MoSi2-SiC composite was synthesized by a pulsed current activated combustion synthesis method within 2 min of one step from mechanically activated powders of Mo2C and Si. Simultaneous combustion synthesis and consolidation were accomplished under the combined effects of a pulsed current and mechanical pressure. Highly dense MoSi2-SiC with a relative density of up to 98% was produced under simultaneous application of an 80 MPa pressure and pulsed current. The average grain size and mechanical properties of the composite were investigated.
Key Words
