摘要：
Specific features of the phase formation in the Fe-Si system within the FexSi1-x (x = 0.5-0.6) concentration range have been investigated. The data obtained by conversion electron Mössbauer spectroscopy suggest that, for the Fe-Si system in the concentration range x > 0.55, a polycrystalline FeSi phase with the CsCl structure is formed under thermodynamically equilibrium conditions upon annealing at T = 250° in this case, the excess (overstoichiometric) Fe atoms are incorporated into the Si sublattice. Previously, the CsCl-FeSi phase was observed only in epitaxially stabilized FeSi/Si(100) layers. © Allerton Press, Inc. 2007.
