摘要
纳米增强体强化轻合金复合材料以其室温强度高、塑性好,耐磨损和优异的高温性能等特点,并兼有结构和功能一体化特性,成为近年来金属基复合材料(MMCs)领域的研究热点之一。实现纳米增强体的弥散分布或构型设计、改善界面结合是纳米增强体强化轻合金复合材料可控制备的重要挑战。本文重点概述了纳米增强体强化轻合金复合材料在制备策略、多尺度混杂增强、增强体构型设计以及新型加工制备技术等方面的研究进展,展望了轻合金复合材料在高强塑性能、构型优化以及结构功能一体化等方面的发展方向。
In recent years, nanomaterials reinforced light metal matrix composites(LMMCs) have been researched widely, due to the enhancement in strength and ductility at room temperature, good wear resistance, excellent high temperature performance and structural-functional integration. However,there remain many challenges in developing high-performance nanomaterials reinforced LMMCs to date.The challenges mainly concentrate in the attainment of homogeneous dispersion or a controlled inhomogeneous microstructure of nanomaterials reinforcements, and the formation of the strong interfacial bonding. In the present review, therefore, current developments in fabrication, multi-scale hybrid reinforcement, novel architecture design and new processing method have been addressed. Moreover, further research interests related to the designs of nanomaterials reinforced LMMCs exhibiting high strength and plasticity, optimal architecture design and structural-functional integration have been proposed.
