摘　　要：镁合金是最轻的金属结构材料,然而其强度低、塑性和耐腐蚀性能差,严重限制了其作为轻金属材料在工程领域中的广泛应用。镁基复合材料因具有比强度高、比刚度高、比模量高、质量轻等优异特性,被认为是目前提高镁合金力学性能、实现其工业化应用最具优势的途径之一。本文着重介绍了碳纳米管、石墨烯、Si C等增强镁基复合材料研究现状。从增强体分散、界面结合及其结构稳定性等方面深入分析了目前镁基复合材料存在的瓶颈;从增强体表面改性、基体合金设计、复合材料制备工艺等方面探索了镁基复合材料的设计新思路;提出了镁基复合材料的发展趋势与研究方向。Magnesium alloy is the lightest metal structural material,but its low strength,low plasticity and poor corrosion resistance severely limit its wide application as a light metal material in the engineering field.Magnesium matrix composites are considered to be one of the most advantageous ways to improve the mechanical properties of magnesium alloys and realize their industrial applications because of their high specific strength,specific stiffness,specific modulus and light weight.The article focuses on the current study of magnesium matrix composites enhanced by carbon nanotubes,graphene and SiC.The bottleneck of magnesium matrix composites is analyzed from the aspects of reinforcement dispersion,interface bonding and structural stability.The new ideas for the design of magnesium matrix composites are introduced from the aspects of surface modification of reinforcements,design of matrix alloy,and preparation process of the composite material.Also the development trend and research direction of future magnesium matrix composites are proposed.
