      abstract     = {The limited ductility of laser powder bed fusion (LPBF)
                      Ti-6Al-4V (Ti64) alloys, caused by their brittle
                      α'-martensitic microstructure, significantly restricts
                      their broader application. This study systematically
                      investigates the influence of Mo additions (0, 1, 3, and
                      $5 wt\%)$ on the microstructure evolution, deformation
                      mechanisms, and mechanical properties of LPBF Ti64 alloys.
                      Incorporation of Mo notably transforms the phase composition
                      from purely α'-martensitic (Ti64 and Ti64–1Mo) to a
                      multi-phase structure containing metastable β and α"
                      phases alongside α' (Ti64–3Mo and Ti64–5Mo). Ti64–3Mo
                      exhibits an optimal balance of mechanical properties,
                      achieving significant improvements in uniform elongation
                      $(9.5 \%)$ and maintaining high yield strength
                      (955 MPa). Enhanced ductility in Ti64–3Mo and Ti64–5Mo
                      is attributed to the synergistic activation of multiple
                      deformation mechanisms, including stress-induced martensite
                      transformation in metastable β, and twinning coupled with
                      multiple slip modes in the α' phase. However, early
                      activation of twinning prior to basal slip reduces yield
                      strength. These insights underscore the crucial role of Mo
                      as a compositional modifier, providing a practical approach
                      for engineering strength-ductility combinations in
                      additively manufactured titanium alloys.},
