SiC and Al18B4O33 particle/whisker reinforced (AZ91D) magnesium alloy matrix composites were fabricated by the melt stirring and casting and the squeeze casting. Some composites were fabricated under the semi-solid conditions and extruded at high temperature in order to improve the mechanical properties. The strength and the aging hardness of the composites were investigated. The microstructure was observed in order to investigate the preparation conditions of the composite having salient mechanical properties. Specially, the interface between the reinforcement and the matrix were observed minutely by high-resolution electron microscopy. The reactivity between the whisker and the matrix in the composite is low. The reinforcements in all composites distribute uniformly in the matrix. The density and the strength of the composite increases and the grain size in the matrix decrease by the extrusion.
