Abstract

The equilibrated grain boundary groove shapes for the solid Cd in Bi-Cd liquid solutions were directly observed. From the observed grain boundary groove shapes, the Gibbs-Thomson coefficient for solid Cd (Cd-0.03 at.% Bi) in Bi-Cd liquid solutions has been determined to be (8.28 ± 0.33) × 10 -8 Km with a numerical method. The solid-liquid interfacial energy between solid Cd and Bi-Cd liquid solution has been obtained to be (81.22 ± 7.31) × 10-3 Jm-2 from the Gibbs-Thomson equation. The grain boundary energy for the same material has been calculated to be (154.32 ± 18.52) × 10-3 Jm-2 from the observed grain boundary groove shapes. The thermal conductivities of the solid and liquid phases for Bi- 54.6 at.% Cd system have also been measured. © 2004 Elsevier B.V. All rights reserved.
