The phase equilibriua in the Ni Re Hf ternary system at 1173K were investigated by means of diffusion triple technique and electron microprobe analysis(EMPA). The experimental results indicate that two ternary intermetallics (α and β) and five binary intermetallics (Ni 3Hf, Ni 10 Hf 7, Ni 11 Hf 9, NiHf and NiHf 2) exist in the Ni Re Hf system at 1?173 K. A tentative isothermal section of this system at 1?173 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.

The experimental results indicate that two ternary intermetallics (α and β) and five binary intermetallics (Ni 3Hf, Ni 10 Hf 7, Ni 11 Hf 9, NiHf and NiHf 2) exist in the Ni Re Hf system at 1 • 173 K. A tentative isothermal section of this system at 1 • 173 K was constructed on the basis of an experimental result. The isothermal section consists of nine three phase regions, five of which are supported by the experimental data.
