The isothermal section of the Gd–Ni–V ternary system at 773K

Abstract: The phase equilibria of the Gd–Ni–V system at 773K 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 773K. 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 16at.%, 2at.%, 3at.% and 2.5at.%, respectively, while that of Gd in (Ni), Ni3V, Ni2V, Ni2V3, NiV3 and (V) was less than 1at.%. An isothermal section of the Gd–Ni–V system at 773K has been presented according to the present work. [Copyright &y& Elsevier]
