Abstract: The Ti-Ni-O ternary system was assessed by means of Calphad method using ternary experimental data in previous study. Isothermal sections at 1 173 and 1 273 K were calculated. The result shows that the present calculated results are in good agreement with most of the experimental results. The consistent model parameter set determined in this work may provide theoretical guidance for the deoxidation of TiNi alloy.
