The results show that the CNTs are dispersed effectively by bell jar immersing precast block casting. The maximal tensile strength and the elongation of the AZ31/CNTs composites are enhanced by 41.3% and 119.4%, respectively, and the elastic modulus and micro-hardness are also raised by 67.8% and 66.9%, respectively, when compared with those of the as-cast AZ31 Mg alloys. The CNTs can greatly refine the grains of the composites, playing a good role in reinforcing the matrixes of AZ31 Mg alloy. The fracture sections of the composites mainly consist of dimples and prisms, which demonstrates quasi- cleavage fracture modes.

结果表明：钟罩压块法可以有效地将碳纳米管分散到镁合金熔体中；CNTs对AZ31镁合金的力学性能有较强的增强效果，与本研究中的铸造AZ31合金相比，AZ31/CNTs复合材料的最大抗拉强度和伸长率分别提高41.3%和119.4%，弹性模量和显微硬度分别提高67.8%和66.9%；CNTs对AZ31镁合金基体晶粒的细化作用显著，与镁基体界面结合较好；复合材料试样断口形貌由韧窝和撕裂棱组成，呈现准解理断裂特征。
