Abstract:
The 12 th World Conference on Titanium has seen the presentation of a number of noteworthy 〖JP〗developments that were aimed at achieving cost reductions and/or improved constitutional and microstructural capabilities through the conventional coldcompactionandsinter powder metallurgy (PM) approach. This review discusses several such developments,including the scavenging of oxygen and chlorine from Ti powder compacts during sintering by minor additions of rare earth compounds, the advantages of PM Ti fabrication with TiH2 powder over elemental Ti powder, the efforts to develop ultrafine assintered microstructures from the use of TiH2 powder, the design of sintering pathways for high solute content alloys such as Ti10V2Fe3Al, and the positive implications of microwaveassisted sintering of commercially pure (CP) Ti and Ti alloys.
