Carbon nanotubes (CNTs) reinforced magnesium matrix composite prepared by an improved process was extruded at 350 °C with an extrusion ratio of 20:1. Most CNTs were individually and uniformly dispersed in the as-cast and the as-extruded composites. Moreover; good interfacial bonding was achieved; and Raman spectroscopy showed that the damage to CNTs was insignificant. The addition of CNTs could weaken basal plane texture. Meanwhile; the CNTs evidently improved the ultimate tensile strength; yield strength and Young's modulus of the as-extruded composite. Pulling-out CNTs proved that the length of the CNTs was not large enough to be compatible with the high strength of the CNTs. Grain refinement; load transfer mechanism and Orowan strengthening mechanism play important roles on the increase of the yield strength. The composites fabricated by our process showed high strengthening efficiency of CNTs. © 2014 Elsevier Inc. All rights reserved;
