Abstract

The phase equilibria of the Gd-Ni-V system at 773 K were investigated by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), and electron probe microanalysis (EPMA). The experimental results show no existence of ternary compounds at 773 K. The existence of 14 single-phase regions, 25 two-phase regions and 12 three-phase regions was determined. The maximum solubility of V in (Ni), Gd2Ni17, GdNi5 and GdNi2 was measured to be about 16 at.%, 2 at.%, 3 at.% and 2.5 at.%, respectively, while that of Gd in (Ni), Ni3V, Ni2V, Ni2V3, NiV3 and (V) was less than 1 at.%. An isothermal section of the Gd-Ni-V system at 773 K has been presented according to the present work.
