摘要：Powder metallurgy techniques have emerged as promising routes for the fabrication of carbon nanotube (CNT)reinforced metal matrix composites. In this present work has been made to investigate the mechanical properties of the fabricatedComposites. Al6061 alloys as matrix and Multiwall Carbon Nanotube (MWCNT) as reinforcement (0, 0.5, 1.0 ,1.5,2 ,2.5 & 3weight percentage) have been fabricated by powder metallurgy process. Al6061 powder (200 mesh) and multiwalled carbon nanotubes (Nanoshell.,USA) were procured from different sources available in the market. The two materials were properly mixed fordifferent composition by using ball mill ,to mix uniformly CNT‘s with Aluminium powder. Compacting die was used to compactthe powder by using 40Ton capacity hydraulic press, after compacting the powder in to solid billet. A low cost sintering furnacewas designed and fabricated for current research work. Sintered billets were hot extruded using hot extrusion set up. Sampleswere prepared for various compositions and the samples were investigated for microstructure, using optical microscope and SEMApparatus and also tested for strength
