摘要

利用压铸工艺制备了含碳纳米管的ZM5镁基复合材料试样。研究了碳纳米管含量对镁合金熔体的压铸特性和力学性能的影响。使用金相显微镜观察了加入碳纳米管后复合材料的金相组织及晶粒尺寸

在扫描电镜下观察了碳纳米管的分布状态。结果表明

加入少量碳纳米管对压铸母合金成形性能没有影响。当碳纳米管加入量达到1.3%时

ZM5镁基复合材料压铸试样的抗拉强度达到最大值

为190MPa。当碳纳米管加入量为1.1%时

压铸镁基复合材料试样具有最大的伸长率

为6.25%。在碳纳米管加入量为1.5%时

压铸镁基复合材料试样的硬度（HV）达到最大值

为95.2。

Abstract

Carbon nanotube reinforced ZM5 magnesium matrix composites were prepared by die casting. Effects of carbon nanotubes content on die characteritics and mechanical properties of the composites prepared were analyzed.In addition

effects on grain size and distribution in the matrix alloy were observed by OM（optical microscope）

and distribution of carbon nanotubes in the matrix alloy was observed by SEM（scanning electron microscope）.The results reveal that trace nano-tubes content can be ignored on effects of forming ability of the alloy.With 1.3% carbon nano-tubes

tensile strength of the ZM5 composites can reach 190MPa

and with 1.1% carbon nano-tubes

elongation of the composites is 6.25%

and with 1.5% carbon nano-tubes

the hardness of the composites prepared reach up to Hv95.2.
