In situ metal matrix composites (MMCs) with Mg2Si particulate reinforcement have been developed recently as ultralight materials, In this paper, a brief overview of the physical and mechanical properties of Mg2Si and the current status of research on Mg2Si reinforced MMCs is presented, followed by more detailed information on recent progress in the research group of the present authors. The effects of element additions and processing parameters on the microstructure of the composites obtained by gravity casting are discussed, together with some mechanical property data. MST/4570.
