Peculiarities of phase composition and morphology in nanostructured (Fe_{70}Al_{30})_{1-x}(Al_2O_3)_x (x=64-80 wt.%) powder alloys prepared by self-propagated high temperature synthesis have been studied by ^{57}Fe transmission Mössbauer spectroscopy, scanning electron microscopy, and X-ray diffraction. It has been established that phase composition of alloys has not been affected by Al_2O_3 contribution. Contrary, atomic arrangement in B2 FeAl phase depends on the volume fraction of Al_2O_3 resulting in the migration of Al atoms from B2 FeAl lattice.
