Carbon nanotubes (CNTs) are considered as promising reinforcements for metal matrix composites because of their unique mechanical and thermal properties. High energy ball milling (HEBM) via powder metallurgy has emerged as an effective technique to disperse CNTs in metal powder matrices. Despite the effectiveness in dispersion, HEBM under harsh milling conditions may damage the CNTs. In this study, a planetary ball mill has been employed to disperse 0.5wt% multi-walled carbon nanotubes (MWCNTs) into a titanium (Ti) powder matrix. The results indicated that harsh ball milling conditions created non-sp2 defects in MWCNTs. In-situ formation of TiC depended upon the milling parameters and milling environment. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Source
