Development of high strength magnesium based MMC reinforced with SiC particles for satellite structure applications

The appearance of Metal Matrix Composites has opened a new area in structural design. The possibility of tailoring mechanical properties of structural metals reinforced with particles or fibers into specific spacecraft applications is very appealing. This paper deals with such a MMC, which is based on a magnesium alloy matrix and SiC reinforcement. The technology used is a commercial semi-solid die-casting, which promises a cost-effective solution, The results of the first stage of this research are discussed with a focus on the satellite structure design application. The next steps of this investigation are also presented.
