Abstract
The grain boundary groove shapes for Zn solid solution in equilibrium with Sn-Zn eutectic liquid were observed with a radial heat flow apparatus. From the observed grain boundary groove shapes, the Gibbs-Thomson coefficient, the solid-liquid and the grain boundary energy for the Zn solid solution in equilibrium with Sn-Zn eutectic liquid were determined to be (2.32 ± 0.13)×10−8 Km, (120.87 ± 13.29)×10−3 J.m−2 and (194.76 ± 23.37)×10−3 J.m−2, respectively. The termal conductivity of the eutectic Sn-9 wt% Zn solid solution, κS, was obtained as 74.74 W/Km by using a radial heat flow apparatus. The thermal conductivity ratio of the eutectic liquid to the eutectic solid, R = κL/κS was found to be 0.58 with a Bridgman-type directional growth apparatus. Thus, the value of the thermal conductivity of eutectic Sn-9 wt% Zn liquid solution, κL, was obtained as 43.82 W/Km.
