Titanium alloys like Ti64 combine broad industrial application in high performance parts with high machining costs and long lead times in conventional processing. They make excellent business cases for AM of offering substantial cost advantages and today are widely used for commercial fabrication, with well-studied quasi-static mechanical properties. Here we present the dynamic mechanical response in a material produced via powder bed fusion (PBF) and explore the dependence on the build orientation, and the location on the powder bed as well as the effect of post-treatments of stress relieving and hot iso-static pressing. To enable evaluation of these effects independently, a comprehensive database of flow stresses is generated through cylinders printed in 3 builds of vertical, horizontal, and 45 ░ orientation, across 5 locations of front-left, front-right, center, rear-left, rear-right on the powder bed, in as-built, stress-relieved, HIP conditions. The dynamic results along with microstructural characterization will be presented.
