Abstract: Polycrystalline alloys Fe$_{2}$TiSn$_{1-x}$Si$_{x}$ (0 $\le x\le$ 1) theoretically predicted as highly efficient thermoelectric materials are experimentally studied. Structural studies show that the partial substitution of Sn with Si results in the formation of a multiphase state in samples with $x>$ 0. Impurity phases in general lead to a significant decrease in the Seebeck coefficient and an increase in the thermal conductivity of Fe$_{2}$TiSn$_{1-x}$Si$_{x}$ samples, which does not allow consideration of these materials as promising thermoelectrics.
