Nanostructured Fe-Co-Mn-Ti-B alloyed powder samples were prepared by mechanical alloying. The structural and magnetic properties are investigated by using x-ray diffraction, scanning electron microscopy, transmission electron microscopy, electron dispersive x-ray spectroscopy and also vibrating sample magnetometer. After 80 h of milling time, the grain size attains the lowest value about 30 nm. The coercivity values show almost an increasing trend up to ending stage of milling time. The magnetic characterizations of annealed milled sample for 100 h milling time at 900 °C demonstrate low coercivity (~33 Oe) and relatively high saturation magnetization (~138 emu/g) values.
