Abstract Scope |
Understanding the dynamics of the laser powder bed fusion additive manufacturing process is critical for establishing location-specific processing-microstructure-property relationships. The highly localized (tens of micrometers) and very short (tens of microseconds) interaction of a laser beam with the powder bed pose a huge challenge to the characterization and understanding of this process. In this talk, I will give an overview of our research on characterizing the dynamics of powder spreading, powder spattering, melt pool evolution, melt flow, defect formation and evolution, and solidification in the laser powder bed fusion additive manufacturing process by using high-energy high-speed x-ray imaging and diffraction, with a focus on defect formation and evolution. |
