Early rare earth elements are added to refractory metal based alloys to absorb residual oxygen in the alloy to enhance ductility and form dispersion strengthening oxides to increase creep resistance. In this work, three binary systems, Ce-Cr, Cr-La and Cr-Y, were thermodynamically assessed based on available experimental data in the literature using the CALPHAD method. Self-consistent and reasonable thermodynamic descriptions for all three systems were obtained.
