The Local Atomic Structure Study of Ordered Fe3Si and Disordered by Grinding Fe75Si25 Alloys with EXAFS and Mössbauer Techniques
Overview & Synopsis
The ordered Fe3Si and disordered Fe75Si25 alloys are studied by X-ray diffraction, Mössbauer spectroscopy and EXAFS-analysis. The X-ray diffraction pattern and Mössbauer spectrum of the Fe75Si25 alloy in comparison with those of the ordered sample give evidence for the set of local atomic configurations of Fe atom and are characteristic for the disordered bcc samples of the Fe-Si system. The comparison of X(k) in these alloys shows noticeable differences, especially in 3.5-5 Å-1region. Combining all the data obtained with the model X(k) one can draw the conclusion that the changes in the Fe atom local structure of the Fe75Si25 alloy are connected with breaking a long-range order but do not correspond to a chaotic distribution of atoms.
