摘      要：Melt processing is a promising process to fabricate Mg-CNTs(carbon nanotubes)composites with high performance and large *** this work,the liquidmixing technique and ball-milling processes as well as the stirring casting method were used to prepare ZM1-1.0 CNTs-L and ZM1-1.0 CNTs-B composites,*** composites were studied using optical microscopy(OM),Raman spectroscopy,scanning electron microscope(SEM),transmission electron microscope(TEM)and room-temperature tensile *** results show that the yield strength(YS),ultimate tensile strength(UTS),elongation and microhardness values of the ***-L composite are improved by 37.3%,29.6%,37.0%and33.3%,respectively,compared with those of ZM1 *** uniform dispersion of CNTs as well as the strong interfacial bonds with the Mg matrix is the main reason for the significant improvement in mechanical properties of the as-cast *** mixing combined with the stirring casting method is favorable to fabricate Mg-CNTs composite with high mechanical properties.
