Al and TiC particles reinforced aluminum matrix composites（TiC/Al

TiC/Al-12Si）were prepared by microwave sintering method.The microscopic morphology

phase constituent

hardness and relative density of the samples prepared were analyzed comparatively.The results show that the microstructure and properties of the samples prepared exhibit satisfy with small particle size by microwave sintering.With adding TiC particles

the growth of the matrix grains is inhibited.In TiC/Al-12Si composites prepared by the microwave sintering

TiC is relatively uniformly distributed with existence of the silicon phase in the shape of bar strip and sheet

and a new stable phase Al9 Si can be observed.The morphology and distribution of the reinforced phase TiC are relavant with the different matrix materials.
