据报告，在 30 至 270 °K 的温度范围内对钯、银和这些金属的五种合金的热膨胀进行了干涉测量。实验不确定性从 270 °K 时的约 1% 上升到 30 °K 时的 15%。热膨胀随浓度的变化是非线性的，并且变化的形式在所覆盖的范围内基本上不受温度的影响。已经发现合金的相关热力学性质具有一定程度的相关性，并且需要在原子尺度上建立二元合金热膨胀的严格理论。
Interferometric measurements of the thermal expansion of palladium, silver and five alloys of these metals are reported in the temperature range 30 to 270 °K. The experimental uncertainties rise from approximately 1% at 270 °K to 15% at 30 °K. The variation of thermal expansion with concentration is non-linear and the form of the variation is not substantially affected by temperature in the range covered. A degree of correlation has been found with related thermodynamic properties of the alloys, and the need has been established for a rigorous theory of the thermal expansion of binary alloys on an atomic scale.
