| Abstract Scope |
High-speed synchrotron x-ray imaging and diffraction are powerful tools for characterizing melt pool dynamics (especially beneath the surface of the melt pool) during laser powder bed fusion additive manufacturing process. In this talk, I will present the key data and insights my research group obtained on (1) melt pool fluctuation/instabilities (including both geometry of the melt pool and melt flow within the melt pool), (2) defects formation and evolution, and (3) solidification dynamics. At the end, I will briefly introduce the defects mitigation approaches we developed based on the new mechanisms we discovered and the new insights we obtained from the in-situ characterization study. |
