Abstract

Al6061 MMC’s are quiet popular in engineering applications because of low density and high stiffness. Carbon Nano tube of late, has emerged to be an excellent reinforcement material for aluminium based metal matrix composites. The present work attempts at developing Al6061 based MMC’s using MWCNT’s for reinforcement using powder metallurgy and stir casting techniques. In this study the details of the manufacturing techniques have been discussed. The SEM images and microstructure details from optical microscope are presented for the various compositions of the MMC’s that have been developed. From the SEM images and microstructure of the composites it is observed that there is uniform distribution of MWCNT and good bonding exists between the carbon nano tubes and the matrix, establishing the stir casting technique for production of Al6061-MWCNT metal matrix composites.
