In a bid to fabricate fully densified titanium-based nanocomposites with enhanced mechanical properties, spark plasma sintering (SPS) technique was employed in this study. Nanocomposite powders consisting of Ti6Al4V and multiwall carbon nanotubes (0.5 & 1.0 wt%) was mixed using shift speed ball milling technique. Furthermore, the Ti6Al4V and the nanocomposites were sintered by SPS technique using the sintering parameters of 100 °C/min, 900 °C and 10 min. The effects of MWCNT content on the densification behaviour during SPS and hardness of the nanocomposites was investigated. The results of the investigations showed the effectiveness of the dispersion technique during the nanocomposite powders preparation. The fabricated materials exhibited similar densification behaviours as it was observed that the relative density ranges from 98.2 to 99.3% and the microhardness increased with the addition of MWCNT in the Ti6Al4V matrix.
