Аннотация:Polycrystalline alloys Fe2TiSn1–xSix (0 ≤ x ≤ 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 Fe2TiSn1–xSix samples, which does not allow consideration of these materials as promising thermoelectrics.
