Abstract: The phase equilibriua in the Ni-Re-Hf ternary system at 1173Kwere investigated bymeans of diffusion triple technique and electron microprobe analysis(EMPA). The experimental results indicate that two ternary intermetallics (α and β) and five binary intermetallics (Ni₃Hf, Ni₁₀Hf₇, Ni₁₁Hf₉, NiHf and NiHf₂) exist in the Ni-Re-Hf system at 1173 K. Atentative i sothermal section of this system at 1173 K was constructed on the basis of experimental results. The isothermal section consists of nine three-phase regions, five of which are supported by the experimental data.
