      abstract     = {Binary Ti-Ta and ternary Ti-Ta-Al alloys attracted
                      considerable attention as new potential biomaterials and/or
                      high-temperature shape memory alloys. However, conventional
                      forming and manufacturing technologies of refractory based
                      titanium alloys are difficult and cost-intensive, especially
                      when complex shapes are required. Recently, additive
                      manufacturing (AM) emerged as a suitable alternative and
                      several studies exploited elemental powder mixing approaches
                      to obtain a desired alloy and subsequently use it for
                      complex shape manufacture. However, this approach has one
                      major limitation associated with material inhomogeneities
                      after fabrication. In present work, novel pre-alloyed powder
                      material of a Ti-Ta-Al alloy was additively manufactured.
                      Hereto, electron beam powder bed fusion (PBF-EB/M) technique
                      was used for the first time to process such Ti-Ta based
                      alloy system. Detailed microstructural analysis revealed
                      that additively manufactured structures had a near full
                      density and high chemical homogeneity. Thus, AM of
                      pre-alloyed feedstock material offers great potential to
                      overcome major roadblocks, even when significant differences
                      in the melting points and densities of the constituents are
                      present as proven in the present case study. The homogeneous
                      microstructure allows to apply short-term thermal post
                      treatments. The highly efficient process chain detailed will
                      open up novel application fields for Ti-Ta based alloys.},
