  The Fe48Co48V4 alloy was synthesized in a planetary high-energy ball-mill under an argon atmosphere. The structure, microstructure and magnetic properties of the mechanically alloyed powders were investigated by X-ray diffraction, Scanning Electron Microscopy and a Vibration Sample Magnetometer, respectively. During the mechanical alloying of Fe48Co48V4, inter-metallic Co3V appears. The lattice parameter decreases up to 55 h of milling time with an oscillation and then increases from 55 to 125 h of milling time. The coercivity increases during the milling treatment from 49 to 58 Oe. The saturation magnetization has some fluctuations during the milling treatment and finally reaches similar to 190 emu/g at 125 h. (C) 2010 Elsevier B.V. All rights reserved.

  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. (C) 2009 Published by Elsevier B.V.
