Abstract Scope |
Ti-6Al-4V is the candidate alloy of choice which constitutes the overwhelming majority of worldwide activity on additive manufacturing (AM) of titanium alloys. While these efforts are extremely important, there exists a tremendous potential for designing and exploiting beta titanium alloys for AM. These alloys do not form an embrittling martensitic phase on quenching, and their microstructure and mechanical properties can be tuned over a wide range. AM processing of two candidate commercial beta Ti alloys, the strain-transformable Ti-10V-2Fe-3Al (or Ti-10-2-3) and high-strength Ti-1Al-8V-5Fe (or Ti-1-8-5) (all in wt%), will be considered. These alloys have been processed by directed energy deposition (DED) and laser powder bed fusion (LPBF). The influence of the non-conventional thermo-kinetics of these AM processes on microstructural evolution, including second-phase precipitation (both omega and alpha) in these alloys, and the consequent influence on mechanical behavior will be discussed. |
