The structure of Cu 2 In melts is investigated by the X-ray diffraction method within a temperature range close to the temperature of onset of crystallization. We analyze the structural factors and functions of the radial distribution of atoms computed by the method of Fourier transforms. The results of structural investigations are compared with the literature data on the enthalpy of mixing and thermodynamic activity. It is shown that the short-range ordering structure is microinhomogeneous and has a heterocoordinated distribution of atoms.

Cu2In金属间化合物在预结晶温度范围内的短程有序结构

在接近结晶开始温度的温度范围内，通过 X 射线衍射法研究 Cu 2 In 熔体的结构。我们分析了通过傅里叶变换方法计算的原子径向分布的结构因素和函数。将结构研究的结果与有关混合焓和热力学活动的文献数据进行比较。结果表明，短程有序结构是微不均匀的，具有原子的杂配位分布。
