Abstract: | Mössbauer spectroscopy, X-ray diffraction, Auger spectroscopy, secondary ion mass-spectrometry and chemical analysis were used to study mechanical alloying of Fe and Mg powder mixture with the atomic ratio of 93:7. It has been shown that the process of mechanical alloying involves the formation of nanostructure in α-Fe particles, penetration and segregation of Mg atoms along the α-Fe grain boundaries, formation of the α-Fe(Mg) supersaturated solid solution. |
