Standard enthalpies of formation of ternary phases in the Cu-Ni-Sn system were determined along sections at 25, 41 and 45.5 at.% Sn applying tin solution drop calorimetry. Generally, the interaction of Ni with Sn is much stronger than that of Cu with Sn. Along all sections the enthalpy of formation changes almost linearly with the mutual substitution of Cu and Ni within the respective homogeneity ranges. Thus no additional ternary interaction promoting the formation of further Cu-Ni-Sn phases can be assumed. The results are discussed and compared with literature values relevant to this system.

(Cu,Ni)3Sn, (Cu,Ni)6Sn5-HT 和 (Ni,Cu)3Sn2-HT 的生成焓

Cu-Ni-Sn 系统中三元相的标准形成焓是在 25、41 和 45.5 at.% Sn 处应用锡溶液滴量热法确定的。通常,Ni 与 Sn 的相互作用比 Cu 与 Sn 的相互作用强得多。沿着所有截面,在各自的均匀性范围内,随着 Cu 和 Ni 的相互取代,生成焓几乎呈线性变化。因此,可以假设没有额外的三元相互作用促进进一步的 Cu-Ni-Sn 相的形成。讨论结果并与与该系统相关的文献值进行比较。
