Özet
The variations of thermal conductivity with temperature for Pb-Sn alloys were measured using a radial heat flow apparatus. The variations of electrical conductivity with the temperature for same alloys were determined from the Wiedemann-Franz law by using the measured values of thermal conductivity. According to present experimental results, the thermal and electrical conductivity of Pb-Sn alloys linearly decrease with increasing temperature but exponentially increase with increasing the composition of Sn. The enthalpy of fusion and the change of specific heat for Pb-Sn alloys were also determined by means of differential scanning calorimeter (DSC) from heating trace during the transformation from eutectic liquid to eutectic solid. © 2010 Elsevier B.V.
