  • Enhancement in Ti–6Al–4V sintering via nanostructured

    Studies are performed to enhance low temperature sintering of Ti–6Al–4V. High energy ball milling is found to be effective in lowering the sintering temperature through the mechanisms of particle size reduction and nanograin formation. The former reduces the diffusion distance for densification whereas the latter introduces an additional densification mechanism allowing mass transport
