采用铜模差压压铸的方法成功制备了碳纳米管颗粒增强镁基非晶复合材料,并对其微观结构、压缩性能、断裂强度及断口形貌进行了研究。结果表明,碳纳米管颗粒与非晶基体结合良好,其引入没有明显改变基体非晶合金的玻璃形成能力和热稳定性能;与非晶合金相比,复合材料的最大压缩强度及断裂位移有明显提高。碳纳米管在基体中复合的比较均匀,没有出现大面积团聚,并形成很多韧窝结构。 The microstructure, compressive properties, rupture strength and fracture morphology of carbon nanotubes (PMMA) composites were successfully prepared by die casting of copper die. The results show that the carbon nanotubes with good adhesion to the amorphous matrix, the introduction of did not significantly change the glass forming ability and thermal stability of the matrix amorphous alloy; compared with the amorphous alloy, the maximum compressive strength of the composite material and fracture displacement obvious improve. Carbon nanotubes in the matrix composite more uniform, there is no large area agglomeration, and the formation of a lot of dimple structure.
