AbstractPhase equilibria of the Sm-Nd-Fe ternary system were determined in an isothermal section of 500 degrees C and vertical sections of SmFe2-NdFe2 and (Sm0.86Nd0.12)Fe-x (1.6 <= x <= 2.4) by optical microscopy, X-ray diffraction analysis, electron probe. microanalysis (EPMA), and differential thermal analysis (DTA) techniques. There are four intermetallic phases: (Sm,Nd)Fe-2, (Sm,Nd)Fe-3, (Sm,Nd)(5)Fe-17 and (Sm,Nd)(2)Fe-17 in the Sm Nd Fe ternary system, and no (Sm,Nd)(6)Fe-23 phase exists in this system. The isothermal section of 500 degrees C possesses 7 single-phase regions, 8 two-phase regions, and 4 three-phase regions. The vertical section of SmFe2-NdFe2 contains 2 single-phase regions, 4 two-phase regions, and 7 three-phase regions, and that of (Sm0.88Nd0.12)Fe-x consists of 2 single-phase regions, 5 two-phase regions, and 2 three-phase regions. The peritectic temperatures for (Sm1-xNdx)Fe-2 alloys decrease with increasing the Nd content when x <= 0.5, and the substitution of Nd for Sm makes the stability of (Sm,Nd)Fe-2 phase decrease.
