Alloys from the Ni–Cr–Zr₂Ni₇ partial system have been studied using optical microscopy, X-ray diffraction, DTA, electron microprobe analysis and microhardness measurements. The existence of two quasibinary sections was established. The projection of the liquidus and solidus of the partial Ni–Cr–Zr system in the composition range Ni–Cr–Zr₂Ni₇ was constructed and isopleth 8.8 at.% Zr was built.
