Description
Summary:•The incorporation of Cu particle into the Fe and Ni powder particles formed a composite structure.•The microstructure factors such as the grain size change the properties of FeCuNi powder.•The effect the elements addition on the microstructure, and magnetic properties of FeCuNi powder.•The Relationship between structural, element addition and magnetic properties. 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.
