Abstract

ACCVD grown CNTs via various ACCVD reaction times were used for the fabrication of Stellite-6/CNTs nanocomposites via powder metallurgy technique. Varied wt. % of CNTs (0.5, 1, 1.5 and 2) was used for nanocomposites development. Effects of varied CNTs wt. % on hardness, compression and fracture behaviors of Stellite-6/CNTs nanocomposites were the main investigating aspects of this study. Hardness behaviors of nanocomposites increased up to a critical wt. % of CNTs, after that there were deterioration in these values. There were some healthy impacts of CNTs on compression behaviors of nanocomposites and these enhanced in noticeable values up to a critical wt. % of CNTs. Varied higher wt. % of CNTs had not any influence on the fracture behavior of nanocomposites and it remain unchanged..
