The powder metallurgy technique was used to synthesize magnesium reinforced with up to 0.3 weight percentage of carbon nanotubes (CNTs). The nanocomposites fabricated were extruded at an extrusion ratio of 20.25:1 and then characterized for their physical and mechanical properties. The influences of carbon nanotubes on the physical and mechanical properties of Mg were investigated. The thermomechanical property characterization shows an increase in thermal stability of the Mg nanocomposites with increasing amount of CNTs added. Mechanical property results reveal an improvement in yield strength, ductility and work of fracture with higher weight percentages of CNTs incorporated. An attempt is made to correlate the physical and mechanical properties with the increasing weight fractions of carbon nanotubes in pure Mg matrix.
