Abstract
A few studies have focused on the preparation of metal matrix composites (MMC) reinforced with CNTs. In these composites there is evidence of poor interfacial bonding between the CNTs and the metal matrix, and this may be detrimental to the mechanical properties Furthermore, agglomeration of the CNTs may produce an uneven dispersion within the matrix which reduces their effectiveness. These are the challenges that need to be addressed in optimizing the synthesis of CNT metal matrix composites. In the present investigation, nanocrystalline AA4032 alloy reinforced with CNTs in different fractions was produced by high energy ball milling. The Raman spectra and TEM observations revealed multi-walled CNTs that are used as reinforcement in the composite. TEM observations revealed nanocrystalline matrix of AA4032 alloy composite along with uniform distribution of CNTs.
