在这一部分，本文考虑了晶格参数随合金成分的变化。在不同的温度下，研究了20种含镍量为23% ~ 97%的γ相合金和4种含镍量为3% ~ 16%的α相合金。在室温下，当向镍中加入铁时，镍晶格几乎随其原子组成线性膨胀，直到晶格参数达到最大值3.5895 a，而镍的原子组成为39%。再加入铁，晶格收缩。在高达600℃的温度范围内，研究了γ合金的参数随成分的变化。根据晶格参数的值，计算了纯铁-镍合金在从纯铁到纯镍的整个组成范围内的密度。
In this part of the paper the variations of lattice-parameter with the composition of the alloys is considered. Twenty alloys in the γ phase ranging in composition from 23 to 97 atomic per cent of nickel, and four alloys in the α phase ranging in composition from 3 to 16 atomic per cent of nickel were studied at different temperatures. At room-temperature, when iron is added to nickel the nickel lattice expands almost linearly with the atomic composition until the lattice-parameter reaches a maximum value of 3.5895 A. for an alloy the composition of which is 39 atomic per cent of nickel. On further addition of iron the lattice contracts. The variation of the parameter of the γ alloys with composition was examined at temperatures ranging up to 600°C. From the values of the lattice parameters the densities of pure iron-nickel alloys over the whole range of composition from pure iron to pure nickel were calculated.
