Abstract

The equilibrated grain boundary groove shapes of solid Pb solution in equilibrium with the Pb-Sb eutectic liquid have been observed from quenched sample. The Gibbs-Thomson coefficient, solid-liquid interfacial energy and grain boundary energy of solid Pb solution have been determined. The thermal conductivity values for Pb-5.8 at.% Sb and Pb-17.5 at.% Sb and the thermal conductivity ratio of eutectic liquid phase to eutectic solid for Pb-17.5 at.% Sb alloy at the melting temperature have also been measured with a radial heat flow apparatus and Bridgman type growth apparatus, respectively. © 2011 Elsevier B.V.
