ResumoThis first chapter of the volume largely serves to set the scene for an appraisal of the current status of metal matrix composite (MMCs), with relatively little in the way of detailed information, but extensive cross-referencing to other chapters of the volume, in addition to conventional citation of the literature. The chapter also includes a brief survey of both scientific issues and technological usage of various types of MMC, with some indications of how the landscape has changed since publication of the first issue of Comprehensive Composite Materials in 2000. Particular attention is paid to cermets, which are highly successful in technological terms and are in widespread commercial use: while they should certainly be considered to be type of MMC, they are not specifically covered elsewhere in this volume. Other “special category” MMCs mentioned here include highly porous metals, intermetallic matrix MMCs and graded structure MMCs, although all of these are treated in some detail in other chapters. Finally, there is mention at certain points of the effects of using very fine reinforcement, which is covered elsewhere in the volume only in terms of the processing challenges presented when the fibers or particles concerned are ultra-fine (nanoscale). In fact, while there has been extensive study over the past couple of decades of the potential offered by such reinforcement (in both MMCs and other types of composite system), caveats are identified here concerning expected property combinations, particularly in terms of the toughness of such composites.
