Structural and magnetic properties of FeCuNi nanostructured produced by mechanical alloying

We investigated the magnetic, morphological, and structural properties of FeCuNi. The powder alloy is elaborated by mechanical alloying process for 10 h with varying the Cu content. The aims of this work are to study the effect of Ni/Cu ratio on the magnetic and microstructure properties. The crystallite size decreases with the increase of Ni. The reduction of crystallite size proceeds slowly until 17 nm for 30% of Ni. Coercivity and saturation magnetization increases from 105.4 Oe, 122.568 emu/g to 156.77 Oe, 140.679 emu/g respectively caused by the increase of the concentration of Cu and dislocation density as well as the decrease of the crystallite size.
