About Qilin Guo

Guo's research interests are at the intersection of additive manufacturing, materials science, and advanced in-situ characterization. He is a pioneer in the use of synchrotron-based in-situ X-ray imaging and diffraction to study the physical dynamics of metal additive manufacturing processes, including the formation and evolution of defects such as spatter, porosity, and cracks, as well as heat and mass transfer and phase transformation.

During his Ph.D. studies, Guo focused on characterizing and quantifying the fundamental physics that govern highly dynamic metal additive manufacturing processes, thereby revealing the mechanisms underlying their physical dynamics. His major accomplishments include the characterization of powder spattering, melt pool evolution, and melt flow evolution in the laser power bed fusion additive manufacturing process. Guo also employed in-situ high-energy X-ray diffraction to study the phase transformation dynamics of 17-4 PH steel during rapid solidification. His research has provided crucial insights into the metal additive manufacturing process and could guide the development of more stable and consistent processes.
