The 773 K isothermal section of the Nd-Fe-Sb ternary system

Abstract The 773 K isothermal section of the phase diagram of Nd–Ni–V ternary system was investigated by X-ray diffraction (XRD), optical microscopy, scanning electron microscopy (SEM) and energy dispersion spectroscopy (EDS) techniques. There are in total 14 single-phase regions, 25 two-phase regions and 12 three-phase regions in the 773 K isothermal section. The maximum solid solubilities of V in Ni, NdNi 5 , Nd 2 Ni 7 and NdNi 2 , is about 16.5 at.% V, 2.0 at.% V, 1.0 at.% V and 3.0 at.% V at 773 K, respectively, and that of Nd in Ni, Ni 3 V, Ni 2 V, Ni 2 V 3 , NiV 3 and V does not exceed 1 at.% Nd. No ternary compounds have been observed in this work.
