Thermodynamic Calculation of Phase Diagrams for the Rare Earth Binary Alloys: RE-Nd (RE = La, Ce, Pr, Y) Systems

摘要

In this work, the experimental data of phase equilibria of the RE-Nd (RE = La, Ce, Pr, Y) binary systems in the published literature were investigated firstly, and then the RE-Nd (RE = La, Ce, Pr, Y) binary systems were calculated using the CALPHAD method. The calculation results were compared with the experiment data. The phase diagrams of RE-Nd (RE = La, Ce, Pr, Y) systems could provides important information for the design of novel Nd-Fe-B-based permanent magnets with rare earth elements.
