Abstract Scope |
A commercially available, metastable β-Ti alloy, Ti-10V-2Fe-3Al, was processed via both Laser powder bed fusion (LBPF) technique, using an Aconity MIDI system and a direct energy deposition (DED) technique, using Optomec LENS-750. With regards to titanium alloys, the use of AM technology has been well established; but most of the literature is limited to the α/β alloy Ti-6Al-4V. In the current study, site-specific microstructure and texture analysis, and mechanical properties along and across the build direction will be presented of this metastable β-Ti alloy. A change in the deformation behavior is noted in the sample, going from planar slip in the as-deposited condition to deformation via transformation induced plasticity in the solutionized sample. To put this in context, mechanical properties and deformation behavior of the bulk sample will also be presented. |
