[Abstract]:The development of metal matrix composites has been promoted to higher strength, better ductility and better processing. Around this goal, the research focus in recent years is mainly multi-scale strengthening, nano-carbon material enhancement and heterogeneous configuration design. The research progress of metal matrix composites is introduced. It is pointed out that superfine grain and superfine particles can obtain high strength and good plastic toughness. Nano-carbon materials have high comprehensive properties and high efficiency and diversity to metal strengthening. Heterogeneous configurations have high feasibility in exerting the reinforcement of nano-carbon and ceramic phases and digging the performance limits of composite materials. At the same time, the challenges faced by these studies are pointed out, as well as the necessity of developing configuration simulation, nanocrystalline carbon-metal interface simulation, and the development of macro fabrication techniques in the future. It can be predicted that the research and development of metal matrix composites has entered a new stage and has become an important direction in the development of high performance materials.
