Accurate structure information of highly reactive melts has been obtained by applying conical nozzle levitation technique as a containerless method. The total structure factor extracted for the liquid Zr50Cu50 alloy above its melting temperature shows a particular shoulder at the high-Q side on the second peak as well as the liquid Zr70Cu30 alloy. This feature of structure factor is similar to those of structure factors observed in deeply undercooled metallic liquids or metallic glasses, in which local icosahedral short range ordering was found to exist. With the use of reverse Monte Carlo simulation analysis, it was demonstrated that short-range ordered clusters exist even in the equilibrium liquid state of Zr70Cu30 alloy., 共催: 日本学術会議, Meeting sponsors: The Science Council of Japan, The Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS)(JAXA), 資料番号: AA0064113047}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {ガスジェット浮遊法を利用した金属ガラス形成合金の液相構造解析}, volume = {22}, year = {2006} }
