Description Nanocrystalline Fe10 %Zn and Fe30 %Zn alloys have been prepared from pure elemental powders by
mechanical alloying processing in a high energy planetary ball-mill. Microstructural, structural, and magnetic
characterizations of the powders were investigated by X-ray diffraction, and vibrating sample magnometer.
The crystallite size reduction to the nanometer scale is accompanied by an increase in the atomic
level strain. The reaction between Fe and Zn leads to the formation of a bcc Fe(Zn) solid solution with a
lattice parameter close to (0.2912 nm for Fe30 %Zn and 0,2885 nm for Fe10 %Zn) after 5 h of milling. The
complete dissolution of the elemental Zn powders in the a-Fe lattice gives rise to the formation of a highly
disordered Fe(Zn) solid solution, where a-Fe(Zn) nanograins have a crystallite size of (229,29 Å for
Fe10 %Zn (24 h) 30,09 Å for Fe30 %Zn (24 h), on prolonged milling time. The coercivity and magnetization
values are 18,90 (Fe10 %Zn)Oe and 26,59 (Fe30 %Zn) emu/g, respectively, after 24 h of milling.
