Abstract : Conventional metallic materials have been tailored in the past close to their ultimate properties. New technological requirements ask for further improved materials. Metal-Matrix Composites (MMC) promise to reach this goal. MMC (Metal-Matrix Composites) can be described as materials whose microstructure comprise a continuous metallic phase (the matrix) into which a second phase has been artificially introduced during processing, as reinforcement. Presently the interest in MMC is primarily focused on light alloys reinforced with a fibrous or particulate phases to achieve major jumps in selected mechanical properties or thermal stability. This new interest is mainly related to the fact that ceramic based reinforcement constituents became recently available, which are comparatively inexpensive. Al2O3- (Aluminum Oxide) or SiC (Silicon Carbide)-based fibres, whiskers and particles, but also carbon fibres are used to reinforce aluminium, magnesium or titanium matrix alloys.
