Abstract

The isothermal section of the phase diagram of the Gd–Co–V ternary system at 773 K was investigated by X-ray powder diffraction (XRD), metallographic analysis, electron probe microanalysis, and differential thermal analysis (DTA) techniques. The isothermal section consists of 14 single-phase regions, 26 two-phase regions and 13 three-phase regions. The solid solubilities of V in the compounds Co17Gd2, Co3Gd, Co2Gd, Co7Gd12 and CoGd3 were about 10.0, 2.0, 6.0, 1.2 and 5.3 at.% V, respectively. It was found that there are some homogeneity range in the only ternary compound of GdCo12−xVx with x = 2.6–3.7 at 773 K. No solubility of Gd in compounds Co3V, σCoV or CoV3 was observed. There is no solubility of V in Co7Gd2 or Co3Gd4 observed at 773 K.
