A nanostructured disordered Fe(Al) solid solution was obtained from elemental powders of Fe and Al using a high-energy ball mill. The transformations occurring in the material during milling were studied with the use of X-ray diffraction. In addition lattice microstrain, average crystallite size, dislocation density, and the lattice parameter were determined. Scanning electron microscopy was used to examine the morphology of the samples as a function of milling time. The thermal behaviour of the milled powders was examined using differential scanning calorimetry. The results, as well as dissimilarity between calorimetric curves of the powders after 2 and 20h of milling, indicated the formation of a nanostructured Fe(Al) solid solution.
