| Abstract: | Conversion electron Mössbauer spectroscopy and X-ray diffraction have been used to investigate the modifications induced by room-temperature irradiation with 360 keV C? ions on a Fe0.86Mn0.14 alloy. The data show that the irradiation produces γ-FeMn along with an increase in the amount of α-FeMn at the expense of ∈-FeMn, both originally present. The initial distribution of Mn atoms in the α-FeMn martensitic phase is observed to change after irradiation. |
