摘要：
We have used Mossbauer spectroscopy to study the influence of Si addition to Fe60Al40 composition without changing the iron content of the alloy. The study has been performed in ordered and mechanically deformed samples. This work shows that the B2 structure present in ordered Fe60Al40 alloy does not change with Si introduction in the studied ternary alloys. However, the binary Fe60Si40 alloy shows D03 and B20 structures. Mechanical deformation of the ordered samples induces a clear change of the Mossbauer spectra of binary alloys with the presence of new sextets or variation of the previous ones; however, the Mossbauer spectra of the studied ternary alloys are very similar to the ordered ones.
