Abstract
In the present study, nanostructured Fe-30wt.% Mn alloys produced by mechanical alloying of Fe and Mn powders mixture. The phase composition and morphology of nanostructured powder were analyzed by X-ray diffraction and scanning electron microscopy. It was found that by milling time up to 10h, crystallite size was decreased to 6nm, on the contrary lattice strain was increased. Solid solubility levels were determined from changes in the lattice parameter values. The lattice parameter increases slightly from 0.28167 to 0.35776nm. Increasing milling intensity by higher ball to powder mass ratio resulted in Fe-Mn alloy formation with smaller crystallite size. The SEM results showed that, plate like particles were formed in initial milling time and particles morphology was changed to equiaxed form in final stage of milling process.
