Dr. Benjamin Stegman successfully completes his PhD!

Hats off to Dr. Benjamin Stegman who has successfully completed his PhD! Dr. Stegman was advised by Professor Xinghang Zhang, and his research explored additive manufacturing (LPBF) of Ni-based superalloy 718 and how varying the process parameters and oxide additives would change the microstructure, thermal stability and high temperature mechanical performance. These materials and knowledge were then used to examine various microlattice designs and their extrinsic effect on the mechanical response. A unique deformation mechanism of crystallographic rotation due to shear strain accumulation was identified in the bending dominant microlattices. After graduation Ben is staying on as a Post-Doc working on a new project investigating methods to overcome printability issues of additively manufactured tungsten and ceramic components.
