| Abstract Scope |
There exists a need to develop rare-earth reduced magnets with minimal amounts of critical metals. When valuable rare earth elements are mined, Ce is often extracted as a co-product which can be used to produce low-cost Ce-containing permanent magnets. Thermodynamic modeling based on the CALPHAD (CALculation of PHAse Diagrams) method is used to predict the phase stability of materials systems. Using this method, the thermodynamics of Ce-Fe-X system are explored as rare-earth reduced magnet systems and coupled with experimental and density functional theory (DFT) data to assess Gibbs energy functions using ESPEI and PyCalphad software.
