Research

Most of Mackenzie's research has been investigating how the feed material is transformed and deposited into the final layer during additive friciton stir deposition. In order to “see” the material flow, we put a tracer material in the feed rod as a marker. Using X-ray computed tomography (XCT), we see a 3D representation of the tracer material’s final position. This, along with modeling, helps us determine the material's flow path. We also investigate the microstructure evolution using electron backscatter diffraction (EBSD), in an effort to uncover the mechanisms involved in this high temperature plastic deformation process. This research is expected to lay the groundwork for strain and strain rate estimation, microstructure evolution, and more process control in additive friction stir deposition.
