Phase Composition and Structural Features of Mechanically Alloyed Iron-Manganese Alloys

摘要

X-ray diffraction and Mossbauer spectroscopy were used to study Fe-Mn alloys prepared by mechanical alloying. It was shown that the mixing of components at the atomic scale during mechanical alloying occurs in a certain correspondence with the equilibrium phase diagram, but the field of solid solutions is broadened and, correspondingly, the two-phase fields are narrowed. The alloys are characterized by a high density of lattice defects. A substantial concentration of stacking faults was observed in fcc alloys.
