44th Annual Review of Progress in Quantitative Nondestructive Evaluation, Vol. 37, AIP Conference Proceedings, July 2018

This study examines the use of acoustics to monitor and detect variations in machine state and deposition parameters within directed energy deposition metal additive manufacturing. QCML worked with Iowa State University on this research.

Scripta Materialia, Vol. 155, pp. 104-108, July 2018

This study found that 316L stainless steel fabricated through a metal powder bed fusion 3D metal printing process enabled conversion of normally detrimental oxides into beneficial nano-scale particles that strengthened the material and restricted grain growth during post-processing. QCML worked with Northwestern University and University of Pittsburgh on this research.

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.
