Fabrication and Characterization of Magnesium Matrix Nanocomposites Reinforced with Multiwall Carbon Nanotubes

Jayakumar Jayaraman


Multiwall Carbon Nanotubes (MWCNTs)-reinforced magnesium nanocomposites were fabricated through powder metallurgy route and then hot extruded as secondary process. CNTs were added by 0.5, 1 and 1.5 wt% with magnesium powders and ball milled to obtain a homogeneous mixture. The effect on mechanical properties of Mg nanocomposites due to the reinforcement of MWCNTs was investigated. The effect of mixing through high-energy ball milling, sintering temperature and extrusion process on the mechanical properties is explored. Mechanical property characterization reveals an improvement in 0.2% YTS, UTS, hardness with higher weight percentages of CNTs incorporated in the Mg matrix without affecting ductility.
