This work firstly presents detailed evidence of the fcc-type miscibility gap in the Cu-Ni-V system at temperatures between 1000 °C and 1100 °C. The phase equilibria, phase transformation behavior and microhardness of the (Cu0.5Ni0.5)100-xVx (at.%) (x=2, 4, 6, 8, 10, 12) alloys have been investigated by electron probe microanalysis, X-ray diffraction, differential scanning calorimetry and Vickers hardness tester, confirming that the fcc-type miscibility gap exists in the Cu-Ni-V system at temperatures between 1000 °C and 1100 °C. The obtained results will not only help to well understand the strengthening mechanisms in the Cu-Ni-V alloys at high temperatures, but also to effectively develop new high-temperature spinodalhardened Cu-Ni-V base alloys in the future.
