## Description

- description: 'For the Nd-Fe-B permanent magnets, a prototype thermodynamic database
    of the 8-element system (Nd, Fe, B, Al, Co, Cu, Dy, Ga) was constructed based
    on literature data and assessed parameters in the present work. The magnetic excess
    Gibbs energy of the Nd2Fe14B compound was reassessed using thoroughly measured
    heat capacity data. The Dy-Nd binary system was reassessed based on formation
    energies estimated from ab initio calculations. The constructed database was applied
    successfully for estimations of phase equilibria during the grain boundary diffusion
    processes (GBDP) and the reactions in the hydrogenation decomposition desorption
    recombination (HDDR) processes. '
