Presenter: Sarah Wolff, PhD, Ohio State University
Location: ERF 1043 or online at Zoom.
Abstract: Laser-based additive manufacturing is promising for its fabrication of complex, multi-material metallic parts with superior mechanical parts for applications in aerospace, energy, and biomedical industries. However, porosity in is common due to rapid solidification and can pose obstacles in qualification and certification. This talk will discuss the fundamental interactions that lead to porosity in the process. High-speed synchrotron X-ray imaging (up to 80,000 fps) experiments at the 32-ID beamline at the Advanced Photon Source show porosity mechanisms and material mixing in real-time.
Speaker Bio: Dr. Sarah Wolff is an assistant professor in the mechanical and aerospace department at Ohio State University, and manufacturing enthusiast. Her previous roles include an assistant professorship in the industrial and systems engineering department at Texas A&M University and an Enrico Fermi Fellow at Argonne National Laboratory. She graduated from Northwestern University in 2018 with a PhD in mechanical engineering. Dr. Wolff's expertise is in metal additive manufacturing and laser processing, particularly in the areas of situ monitoring, high-speed X-ray imaging, image processing, and microstructural characterization.
