Determination of the 850 °C isothermal section in the Co-Ni-Ti system

  • Published:
Journal of Phase Equilibria

Abstract

The isothermal section of the Co-Ni-Ti system at 850 °C was determined by using diffusion couple specimens and equilibrated alloys, which were analyzed by optical microscopy, X-ray diffraction (XRD), and electron probe microanalysis (EPMA) techniques. This isothermal section consists of 9 single-phase regions, 12 two-phase regions, and 4 three-phase regions. The 9 single-phase regions include αTi solid solution, βTi solid solution, Ti2(Co, Ni), Ti(Co, Ni), fcc-(Co, Ni) solid solution, and solid solutions based on TiCo2(hexagonal), TiCo2(cubic), TiCo3, and TiNi3. No ternary Co-Ni-Ti compound was found.
