810 Microstructure and Mechanical Properties of SiC Reinforced Magnesium Alloy Composites prepared by Spark Plasma Sintering

Abstract

High densed SiC reinforced magnesium alloy composites could be obtained by using spark plasma sintering technique. The incorporation of harder SiC particulate either in magnesium matrix or AZ31 matrix improved the properties of composites. However, high weight percentages of SiC lead to agglomerate in the matrix and diminished the mechanical properties of the composites. Distribution of SiC is influenced by particle size of the starting materials for sintering and relate to mechanical property of the composite.
