摘要

本文报道了液态Na-Cd和Na-In合金的自由能和混合熵及其相关热力学性质的新测量方法。结果表明，在富Na区合金中存在某种短程有序的Na，而在富Na区合金中存在相分离的趋势。这些矛盾的特征可以用合金中的交换能来解释，交换能随Na浓度的变化而变化。

Thermodynamic properties of liquid Na-Cd and Na-In

New measurements of the free energy and entropy of mixing and the associated thermodynamic properties of liquid Na-Cd and Na-In alloys are reported. It is inferred that there exists some kind of short-range order of Na, whilst there is a phase separation tendency in the alloys in the Na-rich region. These contradictory features are interpreted in terms of the interchange energies in the alloys which vary as a function of Na concentration.
