Mössbauer spectroscopy at 119 Sn and 57 Fe nuclei was used to study thermally induced processes of phase formation in two-layered systems Sn(4 μm)-Fe(10 μm) obtained by ion-plasma deposition. The layered systems were subjected to sequential isothermal annealings at 550°C and 700°C to show the formation of intermetallic compounds FeSn and Fe 3 Sn 2 and of an α-Fe(Sn) solid solution. It has also been shown that the nature of the phase transformations is determined by a change in the local concentration of tin in the sample in the process of diffusion of the atomic components. Thermally stable spatially inhomogeneous systems FeSn/α-Fe(Sn) and Fe 3 Sn 2 /α-Fe(Sn) have been obtained.
