| Abstract Scope |
Wire directed energy deposition (W-DED) is a common additive manufacturing (AM) process for large format titanium components. Two of the most common W-DED processes are Wire Arc Additive Manufacturing (WAAM) and Electron Beam Additive Manufacturing (EBAM). W-DED processes of Ti-6Al-4V have been shown to form large columnar prior beta grains that encourage continuous alpha grain formation along the grain boundaries which often results in severe anisotropy and low ductility. This work explores several heat treatments, including HIP, to understand if convincing benefits to the resulting microstructure and tensile properties of WAAM and EBAM Ti-6Al-4V could be obtained. Mechanical properties were found through a high throughput tensile testing procedure in order to generate statistically relevant data sets. Mechanical property results will be discussed in context of microstructural evolution and will be compared to conventionally processed Ti-6Al-4V.
