“…Thermocouples were then placed into specimen by inserting thermocouples through the hole of cold plate. Then, top and bottom copper plates include the specimen were placed together into hot and cold stages (Gündüz and Hunt,1985;Maraşlı and Hunt, 1996;Valder, 1954;Ocak et al, 2008;Ata Esener et al, 2019;Akbulut et al, 2008;Akbulut et al, 2009;Keşlioğlu et al, 2006;Karadağ et al, 2018;Altıntas et al, 2016;Pietenpol and Miley, 1929).…”

In this study, the contribution of phonon to the thermal conductivity in the In-Bi (Indium-Bismuth) system due to its composition variation was determined from their electrical and thermal conductivity measurements. Because of the common usage of In-Bi system in many technological applications, thermal and electrical conductivity variations with temperature for different compositions of Bi component were measured. Four-Point Probe (FPP) and Linear Heat-Flow (LHF) methods were used for electrical and thermal conductivity measurements respectively. Intermetallic systems' electrical conductivity values were determined between 0.8524 (1/Ω m) ×10 6 and 2.8381(1/Ω m) ×10 6 and thermal conductivity values were found between 14.50 (W/Km) and 35.93 (W/Km) at the melting temperature. Electron and phonon contributions to the thermal conductivity were calculated by using Wiedemann-Franz Law (WFL) from the measured values. The temperature coefficients values () of electrical and thermal conductivity were calculated between 0.46-2.54 (K-1) x10-3 and 1.29-4.34 (K-1) x10-3 respectively. In order to observe microstructure of the Bi-In intermetallic alloy Scanning Electron Microscopy (SEM) and to determine the composition of the phases in the structures, Energy Dispersive X-Ray Analysis (EDX) were used. Also melting temperatures (349.03 K-387.24 K), enthalpy of fusion (17.97 J/g-42.37 J/g) and specific heat change (0.159 J/gK-0.372 J/gK) of Bi-In alloy systems were measured by using Differential Scanning Calorimeter (DSC).
