Experimental investigation on mechanical properties of Multi Wall Carbon Nanotubes (MWCNT) reinforced aluminium metal matrix composites

The aim of this research is to obtain better micrographs and to perform the mechanical characterization of Multi Wall CarbonNanotubes (MWCNT) consolidated aluminum matrix composite (AMC). This research is focused on the mechanical behaviorand microstructure characteristics in MWCNT consolidated aluminum matrix composites. The composites of MWCNT/Alwere successfully fabricated using powder metallurgy (PM) mechanical alloying (MA) sintering. X-ray diffraction (XRD) andScanning electron microscopy (SEM) micrographs were utilized in order to determine the porosity, density and hardnesscharacteristics to observe if they are affected or not concerning the performance of composites in different reinforced %MWCNT rate conditions. Along with SEM and XRD studies, this study details the homogeneous distribution of nanotubeswhich showed no evidence of decomposition; this was supported by a successive increase in hardness and abrasion resistance. This increase in abrasion resistance and hardness can be accredited to the further activation of the slip system due to thepresence of MWCNTs. Based on the conclusions of this study, the authors determined that the mechanical alloying sinteringmethod provides promising results for the mechanical alloying fabrication of MWCNT/Al composites, especially due to thedifferent % rate reinforced up capabilities.
