Strengthening mechanisms of metal matrix composites

The strengthening mechanisms and strength prediction have always been the focus of investigation, because these are critical to the design of metal matrix composites (MMCs). Numerous strengthening mechanism and theoretical models have been developed to correlate the mechanical behaviors of MMCs with their microstructure characteristics, but no one accords with the experimental results very well. An overview of recent studies on strengthening mechanisms and models for MMCs is presented. The disadvantages, appropriate research orientation are also discussed.
