The Ni-Al-Ce ternary system has been thermodynamically optimized in order to be integrated into the database for Ni-base alloys containing rare earth elements. A comprehensive set of thermodynamic parameters including all the ternary intermetallic compounds have been obtained. The calculated enthalpies of formation for ternary compounds by the present work are consistent with values from other sources. Isothermal sections at 1073 and 773 K and liquidus projection have been calculated. Ternary phase equilibria have been well reproduced compared to experimental data.
