Experimental determination of thermal conductivity and interfacial energies of solid Pb solution in the Pb–Sb eutectic system

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.
