【Abstract】 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.更多还原
