Recently, we used the speciality synchrotron X-ray beamlines housed at the Diamond Light Source, UK and Swiss Light Source, Switzerland to study in-situ the highly transient phase changes phenomena occurred during the metal solidification processes under an electromagnetic field. The ultrafast synchrotron X-ray tomography techniques were used to reveal how exactly electromagnetic pulses alter the growing directions of primary intermetallic phases and the eutectic phases. The huge amount of dataset obtained from the real-time synchrotron X-ray experiments allow the time-evolved 3D phases under the applied external fields to be studied in-situ, revealing many highly dynamic phenomena concerning phase changes and evolution in metal solidification processes that cannot be obtained by the traditional experimental methods, and opening a new era for quantitative solidification and materials processing research.
