Abstract: Multi-Walled Carbon Nanotubes (MWNTs) reinforced magnesium was prepared using a powder metallurgy technique. Powders were mixed by ball milling (without balls) for 6 h at rotation speed 60 rpm. Samples were compacted at 550 MPa. And sintered at 530°C for 2 h. The magnesium containing 0.1, 0.2, 0.4 and 0.6 vol.% Carbon Nanotubes (CNTs). The physical and mechanical properties such as density, porosity, compressive strength, hardness and wear rate were measured and compared with the unmodified pure magnesium samples values. Results of density referred to the ability to manufacture lightweight composites. The results of mechanical properties revealed that the being of CNTs in the Mg matrix composites significant melioration compressive strength. The best improvement UCS is about (172 MPa) at the volume fraction of 0.4 vol.% carbon nanotube. The effect of CNTs on the micro Hardness (Hv) values has very limited. The wear tests showed that the wear resistance is increased with the increasing of the reinforcement volume fraction of CNTs.
