SiC/Al composites with high volume fraction of SiC were prepared at 1150°C by pressureless infiltration. The volume fraction of SiC was increased by decreasing the amount of starch in the green body. Both the microstructure and the strength of the composites were investigated. The results showed that the strength decreased with the increasing of the particle size and volume fraction of SiC. It was suggested that the interface between the SiC particles, which were not sintered, make of the defects in the composites. The defects led to the decreasing of the strength with increasing of the volume fraction of SiC.

A rapid, pressureless infiltration technique for fabricating SiC-reinforced Al-Si composites is described. The infiltration can be performed by simply dipping a ceramic preform into a molten alloy in an open air environment. This method makes it possible to produce composites that contain a high volume fraction (80%) of a variety of ceramic reinforcements, including particulates and fibers. This technique has potential for low-cost and versatile production of SiC-Al-Si composites for many industrial applications, such as automobile components and electronic packaging.
