- A series of $Fe_{3-x}Ti_xSn$ disordered alloys (where x = 0, 0.25, 0.5, and 0.75) obtained by arc-melting were studied. Directly after the melting all samples were mechanically crashed and in that form examined by the X-ray diffraction and Mössbauer effect methods. In $Fe_{3-x}Ti_xSn$ alloy with x = 0 three phases exist: FeSn (B35), $FeSn_2$ (C16) and Fe(Sn) (A2). The contributions of these phases decrease very fast in aid of ternary Fe-Ti-Sn alloys with the B2 and $D0_3$/$L2_1$ types of structure, as Ti atoms concentration increases. It was shown that these ternary alloys consist of four distinct Fe-Ti-Sn phases with contributions depending on the value of the x parameter. The value of hyperfine magnetic field $(B_{hf})$ parameter at the Fe nuclei is equal to about 110 kG for FeSn and $FeSn_2$ phases. However in alloys with A2, B2 and $D0_3$/$L2_1$ type of structure this value changes from 0 kG to 335 kG and can be considered (in the first approximation) as a function of Fe atoms number in the nearest neighborhood.
