摘　　要：轻质高强高韧铝基复合材料已成为汽车、航空航天及5G通讯等领域轻量化发展的重要基础材料之一。但高强度与高韧性不兼备以及加工成形性差成为限制其发展的瓶颈,铝基复合材料的强韧化成为近年来的研究热点。本文综述了颗粒增强铝基复合材料力学性能的主要影响因素以及强韧化机制方面的最新研究进展,特别是关于增强颗粒的构型化设计对高性能铝基复合材料强韧性的重要影响,以及非均匀材料中的异质变形诱导(HDI)强化新机制,并展望了其未来研究和发展趋势,为开发高性能的铝基复合材料提供理论指导。Lightweight,high-strength and high-toughness aluminum matrix composites have become one of the important basic materials for lightweight development in the fields of automobile,aviation,aerospace and 5G communications.However,high strength and high toughness as well as poor formability have become the bottleneck of its development.The strengthening and toughening of aluminum matrix composites has become a research hotspot in recent years.In this paper,the main factors affecting the mechanical properties of particle reinforced aluminum matrix compo-sites and the latest research progress in the toughening mechanism are reviewed.It includes the important influence of the configurational design of reinforced particles on the strength and toughness of high-performance aluminum matrix composites,and the new mechanism of heteroge-neous deformation induction(HDI)reinforcement in non-uniform materials.And the important development trend is prospected,which will provide theoretical guidance for the development of high performance aluminum matrix composites.
