The liquidus and solidus for the Ni-rich side of the Ni-Nb and Ni-Ti systems on a region of Ni-Nb and Ni-Ti systems of <10 mass% Nb or Ti were measured in order to establish the phase equilibria between the liquid and fcc phases. The thermodynamic parameters for both systems were reassessed based on the experimental data. The calculated liquidus and solidus agree well with the measured values of Ni-base superalloys as well as the present binary data.
