Abstract: The results of experimental investigation into Fe$_{2}$Ti$_{1-x}$V$_{x}$Sn alloys ($x$ = 0, 0.06, 0.15, and 0.2) are presented. It is established from the temperature dependences of the electrical conductivity, Seebeck coefficient, and thermal conductivity that the studied compositions exhibit the transport properties typical of semiconductors, while the partial substitution of titanium atoms by vanadium atoms leads to a change in the conductivity from $p$-type to $n$-type; the undoped Fe$_2$TiSn sample possesses the best thermoelectric characteristics.
