Formation of Mn-doped iron silicides by ball milling

Using X-ray diffraction (XRD) and Mossbauer spectroscopy, we have studied the sequence of phase formations in the solid Mn-doped iron silicide series Fe1−xMnxSi2, with 0.00 ≤ x ≤ 0.12, in samples prepared by mechanical alloying from the pure elements. The milling was carried out at room temperature...

description Using X-ray diffraction (XRD) and Mossbauer spectroscopy, we have studied the sequence of phase formations in the solid Mn-doped iron silicide series Fe1−xMnxSi2, with 0.00 ≤ x ≤ 0.12, in samples prepared by mechanical alloying from the pure elements. The milling was carried out at room temperature in Ar atmosphere in a horizontal mill for 15 h. The XRD patterns display broad lines, which can be ascribed to stable and metastable iron silicides like β-FeSi2, ɛ-FeSi, α-FeSi2, MnSi, and Si. The set of hyperfine parameters obtained support the coexistence of β-FeSi2, α-FeSi2 and ɛ-FeSi, in agreement with the XRD results. No replacement of Fe by Mn atoms in the regular sites of β-FeSi2 has been observed.
