By using high pure Magnesium (99.9 wt% )as matrix and multi-walled bended carbonnanotubes ( CNTs ) as reinforced phase, carbon nanotubes/magnesium matrix composite was prepared by thefoundry method under the argon gas protection, and its mechanical properties were tested. The interface structureand component of plating and un-plating carbon nanotubes were analyzed by TEM and EDS, and the action mech-anism was discussed. The experiment results show that the CNTs can strengthen mechanical properties of the nano-tube- reinforced Mg matrix composite, the tensile strength and elongation ratio are greatly improved. Furthermore,the plating CNTs are better than un-plating CNTs in strengthening effects. The tensile strength is inereased by150% and the elongation ratio is increased by 30% than that of matrix when content of CNTs is 0.67 wt% .
