The systematic studies of non-stoichiometric phases from Fe-Al system obtained by selfpropagating
high-temperature synthesis (SHS) were the aim of the present work.
Investigations were performed using 57Fe transmission Mössbauer spectroscopy. The presence
of nonsteichiomertic FeAl, FeAl2 and Fe2Al5 phases was found. It is can be concluded that
the studied powder material is in non-equilibrium state. As the result of milling process the
contents of FeAl phase increase whereas of FeAl2 and Fe2Al5 ones decrease. The determined
crystal structure parameters and the hyperfine interaction parameters are presented and
discussed.
