| Abstract Scope |
The in situ/operando studies on many dynamic material behaviors have been limited by the characterization tools. Synchrotron x-ray techniques have been demonstrated to be very effective for studying real materials under real conditions in real time. In particular, the high-flux hard x-rays generated at the third-generation high-energy synchrotron facilitates allow imaging of dynamic structure evolution in bulk materials with extremely high spatial and temporal resolutions. At the Advanced Photon Source, we recently applied high-speed x-ray imaging to study multiple metal additive manufacturing processes. By taking advantage of the short pulse and diverse time structure of the source, high-resolution imaging experiments with min exposure time set by the natural width of the pulse (~100 ps) and max frame rate set by the bunch repetition frequency (6.5 MHz) can be performed, which enables quantitative measurements of many dynamic structure parameters during laser-based and binder jetting additive manufacturing. |
