【 摘 要 】

The grain boundary groove shapes for the Cadmium (Cd) phase in equilibrium with the Lead (Pb)-Cd eutectic liquid were obtained with radial heat flow apparatus. From the obtained grain boundary groove shapes, the Gibbs-Thomson coefficient, solid-liquid and grain boundary energy for the Cd phase in equilibrium with the Pb-Cd eutectic liquid were determined to be (8.35 ± 0.41) x 10-8Km, (128.00 ± 12.8) × 10-3Jm-2and (239.33 ± 26.32) × 10−3Jm-2, respectively. The thermal conductivities of the solid and liquid phases at the eutectic composition and temperature were also measured by using radial heat flow and Bridgman-type directional growth apparatus, respectively.
