Influences of Post-Processing, Orientation, and Induced Porosity on the Dynamic Compression Behavior of Ti-6Al-4V Alloy Built through Additive Manufacturing

Journal of Dynamic Behavior of Materials, July 2018

This publication relates to work that QCML performed on the Army Research Lab-Ballistic Protection Program with collaborators at University of North Texas. Samples in a variety of orientations (horizontal, vertical, 45 degrees, along with different build plate locations) and conditions (as-built, stress-relieved, and HIP’d) were fabricated using metal powder bed fusion 3D printing technology. High strain rate behavior was evaluated using a Split-Hopkinson Pressure Bar testing system. The research found that creating some porosity within a 3D printed titanium alloy can provide better energy absorption during ballistic-type impacts, which can result in better protection for soldiers.
