摘要

研究了Al含量对碳纳米管/镁基复合材料显微组织和力学性能的影响。结果表明

当Al含量为8%时

复合材料晶粒细小

并具有最佳的强度、硬度和塑性组合;随着Al含量增加

复合材料中出现粗大的、沿晶界连续分布的金属间化合物Mg17Al12相

导致复合材料的抗拉强度和伸长率下降。

Abstract

Effects of Al content on microstructure and properties of carbon nanotubes/magnesium matrix alloy composites were investigated. The results show that the composites with fine grain exhibits desirable tensile strength

hardness and plasticity with 8% Al content. Coarse Mg17Al12 phase uniformly distributed along grain boundary is generated in the composites

resulting in the decrease of tensile strength and elongation with the increase of Al content.
