Abstract
ACCVD grown CNTs were used for the fabrication of nanocomposites via powder metallurgy technique. Varied wt. % of CNTs (0.5, 1, 1.5 and 2) was used in nanocomposites development. Effects of varied CNTs wt. % on the physical, microstructurel and phase behaviors of nanocomposites were the main investigating objectives of this study. Relatively density of Stellite-6/CNTs nanocomposites varied with the increase of CNTs wt. %. As for as the microstructurel aspects of nanocomposites are concerned, detailed optical and SEM analyses were performed. Through optical microstructure analyses, a region named as Stellite-6/CNTs composites was prominent for the nanocomposites materials as compared to plain material. SEM analyses confirmed the denser microstructures of nanocomposites with the increase of CNTs wt. %. CNTs sustained and no any unwanted phases were detected for Stellite-6/CNTs nanocomposite material after high temperature sintering process.
