ABSTRACT:
A magnesium based metal matrix composite is made from rapidly solidified magnesium alloy powder and SiC particulate using liquid suspension coprocessing or mechanical alloying. The composite is suitable for consolidation into bulk shapes having, in combination, high strength, high stiffness, low density, low coefficient of thermal expansion, and high hardness. The composite is suited for uses in such applications as space and missile guidance and navigation and control system precision components where low density, very high specific stiffness and long term dimensional and environmental stability are principal performance criteria.
