| Popis: | 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. |
