Mössbauer study of the Fe-Si intermetallic compounds

Structural transformation in mechanosynthesized bcc Fe–Al–Si(Ge) solid solutions during heating

“…The B20 phase is FeSi 1−x Al x . The parameters of magnetic interaction of atoms in the lattice of this phase are fairly comparable with the characteristics of the Mössbauer spectrum of FeSi at 720 • C (δ = 0.212 mm/s, E 0 = 0.49 mm/s) [13].…”

Phase stabilization in the Fe1−xMnxSi2 system induced by ball milling

“…The interaction I 3 could be ascribed to the Fe II site of a-FeSi 2 structure [17]. Due to interaction I 1 is shared between a-FeSi 2 and 3-FeSi and the fact that the relative populations of fractions of Fe I and Fe II sites of a-FeSi 2 are strongly dependent on the content of Fe vacancies in the lattice [18,19], it was not possible to extract the relative amounts of a-FeSi 2 and 3-FeSi phases present in the samples. However, according to the X-ray results, only traces of 3-FeSi were present in the B-type samples.…”

On the formation of pure and Pt-doped iron silicides using ball milling

“…= 0.28 1 mm s −1 , δ 2 = 0.07 1 mm s −1 , F 2 = 42 1 %; and I 3 : 3 = 0.50 mm s −1 , δ 3 = 0.28 mm s −1 , F 3 = 16 1 %) associated with the non-equivalent iron sites in the β-FeSi 2 structure[8] and (with minor intensity) with ε-FeSi[13,14]. The α-FeSi 2 -to-β-FeSi 2 transformation is clearly observed in the diffractograms and in the Mössbauer spectra.…”
