摘　　要：用具有超高强度、超高模量及超强化学稳定性的碳纳米管与Mg复合,得到的碳纳米管增强镁基复合材料,即使在CNTs的添加量很少的情况下,只要其分散均匀,CNTs/Mg基复合材料的弹性模量、硬度、屈服强度和抗拉强度都得到大幅度提高。大部分采用液态成形方法制备的CNTs/Mg复合材料的伸长率也同步提高,有很大的发展潜力。从复合体系的设计,复合材料的制备、组织及性能等方面,介绍了有关碳纳米管增强镁基复合材料的研究进展。Magnesium composites reinforced with carbon nanotubes, which possess super high strength, modulus and chemical stabilityed, exhibited a higher elastic modulus, hardness, yield strength and tensile strength with a little CNTs addition under the condition of uniformly dispersedly distribution, and the elongation of the composites prepared by squeezing casting was increased significantly, showing great development potentiality. Progress in carbon nanotubes reinforced magnesium composites from processing, microstructure and properties was reviewed.
