Abstract:
South Africa primarily produces titanium raw material as a TiO2 rich slag of which most is exported, without further value addition to the mineral. Therefore, powder development becomes a significant aspect of research with possibilities of growth within the titanium metal industry in South Africa. Commercially pure titanium has been successfully blended in conventional powder metallurgy processing, but the use of blended elemental powder to produce Ti-6Al-4V powder for metal additive manufacturing alloy parts has not been demonstrated yet. The objective of this study is to determine the feasibility of using blended elemental Ti-6Al-4V powder for use in a powder bed additive manufacturing (AM) system. In this paper a literature review and proposed methodology are presented and the expected outcomes are discussed.
