The constitution of the Ni–Zr phase diagram in the range 25–60 at.% Ni was refined using physicochemical analysis methods (metallography, X-ray diffraction, and differential thermal and electron microprobe analyses). The Zr2Ni and ZrNi phases were shown to melt at temperatures about 100 and 30°C lower than accepted previously. Upon analysis of the published data and our own experimental results, we concluded that the eutectic interaction between the Zr2Ni and ZrNi phases was not adequately confirmed. A modification of the equiatomic cubic phase was found for the first time.

Ni-Zr 相图在 25-60 at.% Ni 范围内

Ni-Zr 相图在 25-60 at.% Ni 范围内的构成使用物理化学分析方法（金相学、X 射线衍射、差热和电子探针分析）进行了细化。Zr2Ni 和 ZrNi 相在比之前接受的温度低约 100 和 30°C 时熔化。根据对已发表数据和我们自己的实验结果的分析，我们得出结论，Zr2Ni 和 ZrNi 相之间的共晶相互作用没有得到充分证实。首次发现等原子立方相的改性。
