dc.description.abstractCarbon nanotubes (CNTs) have recently emerged as materials with outstanding properties. Researchers have investigated their use as reinforcements in polymer and ceramic matrices. However, due to the anticipated fabrication difficulties, the research has been extended to use the material to reinforce metal matrices. In this project, planetary ball milling was used to disperse 2wt% MWCNTs in aluminum (Al) powder. Mechanical alloying (MA) was used to generate a homogenous distribution of 2wt% CNTs within Al powders. The effect of milling time (up to 40 hr) speed (200-250 rpm), ball size (10, 15 and 20 mm) and PCA (stearic acid, methanol) on the morphological development of the powders was investigated subsequently. Powder metallurgy was used for compaction and sintering process in different temperatures (430˚C-594˚C). The results can have important implications for the processing of CNTs reinforced metal matrix composites in aerospace, automotive, electronics industries, etc. Under the investigated mechanical alloying and sintering conditions, morphology and enhancement in mechanical properties were compared with pure aluminum and Al-2wt%CNTs in a same process history.en_US
