In the study, Fe-Mn-Ti-Sn Heusler [Fe2-xMnxTiSn (0≤x≤2)] alloy was selected Fe2TiSn, Fe1.5Mn0.5TiSn, FeMnTiSn, Fe0.5Mn1.5TiSn, Mn2TiSn components were obtained in these ratios for the first time using arc melter melting furnace. Temperature dependent electrical measurements of the obtained samples were determined by four point probe method (FPPT). The electrical resistance values of the samples at 330K were obtained as 0.14-2.25x10-6 (m) and 0.02-0.49 x10-6 (m) at 750 K. In addition, the temperature coefficient of electrical resistivity value was calculated as  (0.03-1.29)x (10-3 K-1). Phases belonging to each composition were determined by examining the XRD peaks. Microstructures of the samples were obtained by SEM, EDX and MAPPING images. Finally, the composition-dependent microhardness measurements of the samples were determined using the Vickers hardness test and the average microhardness values obtained were measured as 481-716 HV0.5.
