Research Abstract
It has been required to understand solidification phenomena in metallic alloys based on direct observation. However, there were still limitations to the direct observations. In this study, time-resolved computed tomography (4D-CT), which uses the synchrotron radiation X-rays, and a thermodynamic-based reconstruction procedure, was developed to observe microstructure evolution during dendritic solidification in Sn, Al, Ni and Fe alloys. The developed technique allowed us to perform the two-dimensional and the three-dimensional observations. An alternative solidification and transformation mode was found in steel solidification, and the transformation significantly influenced the microstructure evolution of austenite grains. In addition, the formation mechanism of graphite nodules in cast iron, and the deformation mechanism of semisolid during solidification were studied using the developed technique.
