The phase relations in the Ti-Nb-Co system are of great importance for the design of high temperature Ti alloys. The isothermal section of Ti-Nb-Co system at 1000 °C has been established using one diffusion couple supplemented with 13 key alloys. Phase relations and ternary solubility of the binary compounds were determined using electron probe microscopy (EPMA), wave dispersive X-ray spectrometer (WDS) and X-ray diffraction (XRD) techniques. There are 19 two-phase equilibria and 9 three-phase equilibria in the isothermal section at 1000 °C. ...
