Phase relationships in the Co-Nb-V ternary system were experimentally examined through electron probe microanalyzer and x-ray diffraction, and the isothermal sections of 1000 and 1200 °C were established. The obtained experimental results also show: (1) the (Nb, V) phase forms the continuous solid solution; (2) niobium solutes into α (Co) and σ-Co2V3 phases with a small solubility; (3) the C36 Laves-phase is stabilized at 1000 °C which is below its stability limits in Co-Nb binary system, and it forms a single phase region at 1000 °C; (4) vanadium has a large solubility in C36 Laves-phase; (5) vanadium and cobalt atoms show the analogous site occupation in C36 Laves-phase.
