Abstract

The atomic-scale structural evolution of Ga_68.5In_21·5Sn₁₀ (wt. %) liquid alloy has been explored utilizing in-situ high-energy synchrotron X-ray diffraction from room temperature (293 K) to around the melting point. During the process of decreasing temperature, bond lengths of dominant atomic pairs decrease, whereas the total coordination numbers of the first nearest neighbor shell increase. This structural transition is ascribed to the redistribution of atoms and/or clusters and the decrease of vacancies induced by decreasing temperature. Our results are supportive for further understanding the atomic-scale structural evolution of liquid alloys at the low-temperature condition.
