| Popis: | X線・中性子散乱法と静電浮遊炉を組み合わせることにより、超高温や過冷却液体の構造を精密に測定することが可能である。本研究は、シリコンやジルコニウムなど高温金属液体の液体構造を測定するために、構造解析用の静電浮遊炉を新たに開発し、高輝度放射光および中性子線を用いた散乱実験を試みた。実験の結果、これらの液体の静的構造因子(過冷却液体状態を含む)を高精度に測定することができた。 The structure of undercooling liquid state is one of the important subjects of materials science. The levitation techniques are powerful tools for the investigation of undercooled liquids. In this research, we developed the electrostatic levitation furnace for the liquid structure analysis due to the neutron and x-ray diffraction methods. The apparatus was tested by using a synchrotron radiation facility, a laboratory X-ray source and a reactor. The structures of several kinds of materials were investigated and the liquid structures can be measured with high precision. 資料番号: AA0049301004 レポート番号: JAXA-RR-05-034E |
