Abstract

The Fe–Nd–Sb system was assessed by means of the CALculation of PHAse Diagram (CALPHAD) technique. The solution phase, liquid, bcc, fcc, dhcp, and rhom, were described by the substitutional solution model. The compounds Fe₁₇Nd₂, Fe₁₇Nd₅, Nd₂Sb, Nd₅Sb₃, Nd₄Sb₃, NdSb, NdSb₂, Nd₆Fe₁₃Sb (τ₁), Nd₃Fe₃Sb₇ (τ₃), NdFeSb₃ (τ₄), and NdFe₄Sb₁₂ (τ₆) were treated as stoichiometric compounds. The ternary compounds Nd₂Fe₅₋_xSb₁₀₋_y (τ₂, x = 1.48, y = 5.12) and NdFe₁₋_xSb₂ (τ₅) were modeled as (Fe,Va)_0.4667(Nd)_0.1333(Sb,Va)_0.4 and (Fe,Va)_0.25(Nd)_0.25(Sb)_0.5, respectively. A set of self-consistent thermodynamic parameters of the Fe–Nd–Sb system was obtained in this study.
