Microstructure and Mechanical Properties of Titanium Matrix Composite Reinforced by Functionalized MultiWalled Carbon Nanotube

Abstract:

In this study, titanium matrix composites (TMCs) reinforced by functionalized multiwalled carbon nanotubes (MWCNTs) , prepared via powder metallurgy (PM) route. The powder mixture was pressed under 310 MPa (cold press), then sintered in vacuum furnace for 2h at 1300 °C . The Optimum mixing time under Ar atmosphere was 2h at mixing speed of 250 rpm. The microstructure of solid-state sintered composite was investigated by scanning electron microscopy and X-ray diffraction analysis. Mechanical properties of TMC were significantly improved by addition of functionalized MWCNTs compared to the pure titanium sample, due to uniform distribution of Un-bundled MWCNTs. in during mechanical alloying process, mixture powder reached ultrafine size.
