| Research Abstract |
In order to clarify a link between the local structures of liquid and solid phases during directional solidification of high-temperature melts over 2000 K, we have developed a laser-heated zone-melting equipment for synchrotron x-ray diffraction experiments. We succeeded in obtaining accurate data of liquid structure of high melting temperature materials such as alumina and Ti. In addition, we demonstrated that precipitation of a metastable phase during solidification of Ti may be detected by obtaining structure data around the interface of liquid and solid phases.
