Comparison of site preferences of 57Co at grain boundaries in Fe-Si and Fe-Al alloys.
Original language description
Emission Moessbauer spectroscopy was applied to the study of grain boundaries in the polycrystalline samples of iron rich Fe-Al and Fe-Si alloys. The results obtained on Fe-Al samples indicate complicated phase and chemical composition along grain boundaries (GBs). Neither homogeneous increase in Al concentration at GBs nor important site preference of Co atoms is observed. A large fraction of Co atoms occupy positions of lower symmetry. The results on Fe-Si show differencies in the chemical compositionin grain interiors (GIs) and at GBs. An increase in Si concentration at GBs is observed there. In Fe-! & at.%Si sample a strong site preference of cobalt atoms at GBs is detected. The diffusing Co atoms prefer the lattice sites, which are expected to beoccupied by structural vacancies in the D03 superstructure.
