Neutron and Mössbauer studies of Fe3−xAlxSi alloys

Abstract

Neutron and Mössbauer measurements are carried out for the Fe3−xAlxSi alloys with x approximately equal to 0.1, 0.2, and 0.3. The alloys exhibit DO3 type of structure in which the excess nonferrous atoms locate preferentially at the so-called B site. The Mössbauer spectra consist of the broadened Zeeman sextets and a low-field part which contribution to the spectra increases with the aluminium content. The origin of this low-field part, as well as the broadening of the line-widths, are discussed. [Russian Text Ignored].
