dc.description.abstract | This paper presents an evaluation of the tensile properties and microstructural
characterization of Ti6Al4V alloy manufactured with three different processing routes; traditional
wrought processing, investment cast and Laser Engineered Net Shaping (LENS). Tensile specimens
were machined from each process and tensile tested at room temperature. Fractured specimens were
characterized using light optical microscopy, stereo microscopy, microhardness and Scanning
Electron Microscopy (SEM) to investigate the microstructural morphology and the structural
hardness variation. The investment cast Ti6Al4V alloy microstructure revealed large equiaxed grains
containing various orientated lamellar colonies. The additive manufactured microstructure revealed
long columnar grains with Widmanstätten αʹ martensite laths and retained β grain boundaries. While
the wrought Ti6Al4V microstructure was observed as smaller equiaxed grains with large colonies of
fine lamellar and transformed β. Additive manufactured specimens had higher yield strength,
ultimate tensile strength and hardness compared to the investment cast and wrought manufactured
