Mg–3Al–1Zn–CNTs composites, with different weight fractions (0.25–1.0 wt%) of carbon nanotubes (CNTs) were successfully fabricated via a powder metallurgy method. The processing parameters were adopted in such a way to have uniform dispersion of short length CNTs without any damage, as well as refined and dissolvedβphases structures throughout the composite matrix. The composite exhibited impressive increase in microhardness (about t 23%) and tensile failure strain value (about t 98%) without significant compromise in tensile strength, compared to the un-reinforced Mg–3Al–1Zn alloy. The synthesized composites can be used in automotive and aerospace industries due to their low density and high specific strength.
