Microstructural evolution and mechanical properties of carbon nanotubes–reinforced TZM composites synthesized by powder metallurgy

A strategy utilizing carbon nanotubes (CNTs) was put forward to prepare Titanium–zirconium–molybdenum (TZM) composites, which comprised Mo–0.5Ti–0.1Zr–0.03CNTs (wt.%), via high–energy ball milling (HEBM), followed by spark plasma sintering (SPS). The microstructural evolution of the TZM composite powders and the sintered samples were characterized by X–ray diffraction (XRD) and scanning electron microscopy (SEM). Their Vickers hardness and...
