Abstract: Magnesium composites containing nano-size silicon carbide (SiC) particulates were synthesized using powder metallurgy technique coupled with a novel microwave assisted rapid sintering. The sintered specimens were hot extruded and characterized in terms of microstructural, physical and mechanical properties. Microstructural characterization revealed minimal porosity and the presence of a continuous network of nano-size SiC particulates decorating the particle boundaries of the metal matrix. Thermal mechanical analysis revealed a marginal reduction in the average coefficient of thermal expansion (CTE) values of the matrix with the addition of nano-size SiC reinforcement. Mechanical characterization revealed that the addition of nano-size SiC particulates lead to an increase in microhardness, 0.2% yield strength (YS), ultimate tensile strength (UTS) and ductility of the matrix. Particular emphasis was placed to correlate the effects of nanosize SiC reinforcement on the microstructural, physical and mechanical properties of monolithic magnesium. Copyright © 2005 by ASME.
