通过对平衡合金和扩散偶的金相和电子探针显微分析，实验确定了 Ag-Bi-Ni 体系中 300、400、500 和 600 °C 以及 Cu-Bi-Ni 体系中 300、400 和 500 °C 的相平衡。差示扫描量热法用于测量相变温度。所有实验结果表明，Ag-Bi-Ni体系中二元金属间化合物的三元元素的溶解度是有限的。然而，二元金属间化合物具有Cu-Bi-Ni系三元元素的一定溶解度。在Ag-Bi-Ni和Cu-Bi-Ni体系中没有发现三元金属间化合物。在测定结果的基础上，对Ag-Bi-Ni和Cu-Bi-Ni体系中的相平衡进行了热力学评估，计算结果与实验数据之间取得了合理的一致性。
The phase equilibria at 300, 400, 500, and 600 °C in the Ag-Bi-Ni system and 300, 400, and 500 °C in the Cu-Bi-Ni system were experimentally determined by metallography and electron probe microanalysis on equilibrated alloys and diffusion couples. Differential scanning calorimetry was used to measure the temperatures of phase transformations. All the experimental results show that the solubilities of the ternary elements of the binary intermetallic compounds in the Ag-Bi-Ni system are limited. However, the binary intermetallic compounds have some solubilities of the ternary elements in the Cu-Bi-Ni system. No ternary intermetallic compound was found in the Ag-Bi-Ni and Cu-Bi-Ni systems. On the basis of the determined results, the phase equilibria in the Ag-Bi-Ni and Cu-Bi-Ni systems were thermodynamically assessed, and reasonable agreement between the calculated results and experimental data was obtained.
