The addition of rare-earth elements (REE), specifically cerium and lanthanum is of interest to improve the mining economics of Nd, Pr, Sm, etc., which are widely used in clean energy technology. Thermochemical modeling using the CALPHAD method (CALculation of PHAse Diagrams) aids in designing alloys for additive manufacturing by predicting the phase-behavior of multi-component systems. A thermodynamic database to investigate Al-Ce alloys has been developed and include the following elements, respectively : Al-Ce-Cu-Fe-La-Mg-Mn-Ni-Si-Zn-Zr. The model is applied to design new alloys with within specified composition ranges and include relevant phases that are empirically known to provide strengthening properties.
