| The nanostructured Fe-Co alloys were prepared by mechanical alloying of elemental powders using a high-energy ball mill. This made it possible to study the structural evolution of the milling product with the grinding time. In addition to previous X-ray diffraction and thermomagnetic investigations, 57Fe based Mössbauer transmission spectroscopy was used for this purpose. Iron was alloyed with cobalt just after one hour of milling and bcc Fe-Co solid solution was formed. The analysis of the hyperfine magnetic field distribution proved that no significant structural changes occurred during further milling. A slight but regular increase in the standard deviation was observed, indicating an enhancement of topological disorder or/and an increase in internal stresses. |
