(Fe50Co50)100−XVX = 0,2,4 alloy powders were prepared by mechanical alloying. The milling times were 4 h, 8 h, 16 h, 24 h, 36 h, 55 h and 125 h, respectively. Structural, micro-structural and magnetic studies were carried out by X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and a Vibration Sample Magnetometer (VSM). The XRD results showed that the inter-metallic compound (Co3V) appears during milling and affects the coercivity, lattice parameter and micro-strain. Crystallite size decreases and reaches approximately 10 nm at 125 h. The coercivity increases during the milling and reaches a maximum at 55 h and then decreases slightly.
