| 摘要 | Carbon nanotubes were blended into a Ti-6Al-4V matrix to synthesize titanium carbide (TiC) in situ, via spark plasma sintering. The microstructure and mechanical properties of both the monolithic Ti-6Al-4V alloys and the TiC/Ti-6Al-4V composites were studied to evaluate the strengthening effects of TiC on the Ti-6Al-4V matrix. The morphologies obtained by scanning electronic microscopy and optical microscopy indicated that the grain size of both the Ti-6Al-4V alloy and the TiC/Ti-6Al-4V composite decreased with increasing planetary ball-milling (PBM) speed, leading to an increase in the hardness of the investigated materials. The compressive yield strength of the monolithic Ti-6Al-4V alloys and the TiC/Ti-6Al-4V composites initially increased and then decreased with increasing PBM speed. The strengthening and fracture mechanisms were studied. |
