论文摘要
合金随着浓度的变化而扩大或收缩，原子体积和合金含量之间的关系是固体的重要特性。众所周知的近似值认为原子体积随浓度（Zen的定律）线性变化，但实际变化更为复杂。在这里，我们使用明显的溶质原子（溶剂）原子和弹性来得出二元固体合金原子体积的显式分析表达式。提出了两个近似值，即连续和终端。研究了22种二元合金系统的Zen法律偏差。
Alloys expand or contract as concentrations change, and the resulting relationship between atomic volume and alloy content is an important property of the solid. While a well-known approximation posits that the atomic volume varies linearly with concentration (Zen`s law), the actual variation is more complicated. Here we use an apparent size of the solute (solvent) atom and the elasticity to derive explicit analytical expressions for the atomic volume of binary solid alloys. Two approximations, continuum and terminal, are proposed. Deviations from Zen`s law are studied for 22 binary alloy systems.
