Abstract
Phase equilibria were established in the Dy–Co–V ternary system at 773 K by X-ray powder diffraction (XRD), differential thermal analysis (DTA) and scanning electron microscopy (SEM). The result shows that the isothermal section consists of 13 single-phase regions, 23 two-phase regions and 12 three-phase regions. The maximum solid solubilities of V in (Co), Dy2Co17, DyCo3, DyCo2, Dy12Co7 and Dy3Co are about 6.5, 10.0, 2.0, 6.3, 1.5 and 5.0 at.% V, respectively. It is found that there is some homogeneity range in the only ternary compound of DyCo12−xVx with x = 1.6–3.8 at 773 K. There is no solubility of V in Dy2Co7 observed at 773 k. The binary compounds Dy4Co3 and DyCo5 are not observed at 773 K.
