Abstract Scope The addition of rare-earth elements (REE), specifically cerium is of interest to improve the mining economics of Nd, Pr, Sm, etc., which are widely used in clean energy technology. Thermochemical models using the CALPHAD (CALculation of PHAse Diagrams) method aid in alloy design for additive manufacturing by predicting the phase-behavior of multi-component systems to achieve the desired chemical makeup of an alloy. Thermodynamic databases to investigate Al-Ce alloys and Ce-Co alloys have been developed and include the following elements, respectively : Al-Ce-Cu-Fe-La-Mg-Ni-Si-Zn-Zr and Ce-Co-Cu-Fe-La. The models are applied to design alloys with within specified composition ranges and include relevant phases that are empirically known to provide strengthening properties. Prepared by LLNL under Contract DE-AC52-07NA27344.
