Time-resolved imaging of electron beam powder bed fusion using an X-ray microscope optimized for white beam radiation. [PDF]
J Synchrotron RadiatA high‐speed X‐ray microscope design optimized for white beam synchrotron radiation enables real‐time in situ imaging of crack dynamics during electron beam powder bed fusion (PBF‐EB) of high‐Z materials. With high temporal resolution and 10 µm spatial resolution, the system reveals previously unobservable crack evolution behavior in Ni‐based ...
