Résumé : 

We investigated the magnetic, morphological, and structural properties of FeCuNi. The powder alloy iselaborated by mechanical alloying process for 10 h with varying the Cu content. The aims of this workare to study the effect of Ni/Cu ratio on the magnetic and microstructure properties. The crystallite sizedecreases with the increase of Ni. The reduction of crystallite size proceeds slowly until 17 nm for 30% ofNi. 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 densityas well as the decrease of the crystallite size
