Abstract Scope |
Metastable beta-titanium (β-Ti) alloys have begun to find increased use over Ti-6Al-4V (wt. %) in the aerospace and defense industries, primarily due to their lower weights and higher obtainable strengths. The ‘metastability’ also allows the possibility of deformation-induced phase transformations, such as transformation induced plasticity (TRIP), to further enhance mechanical properties. Along with the increased use of these alloys, their production by additive manufacturing (AM) has become of interest. To advance our understanding of metastable beta-Ti alloys, simulated powder bed fusion-laser beam was performed on the commercial β-Ti alloy Ti-10V-2Fe-3Al (wt.%) at the Advanced Photon Source at Argonne National Laboratory under varying processing conditions. Residual stresses produced TRIP product in all experiments, differing in degree and by location. The coupling of post-mortem microscopy and thermomechanical simulations with SYSWELD revealed grain orientation and residual stress profile collectively control the as-built structure of this alloy under AM conditions. |
