Özet

The Gibbs-Thomson coefficient and solid-liquid interfacial energy of the solid In solution in equilibrium with In Bi eutectic liquid have been determined to be (1.46 0.07) × 10-7Km and (40.4 4.0) × 10 -3Jm-2 by observing the equilibrated grain boundary groove shapes. The grain boundary energy of the solid In solution phase has been calculated to be (79.0 8.7) × 10-3Jm-2 by considering force balance at the grain boundary grooves. The thermal conductivities of the In-12.4at.% Bi eutectic liquid phase and the solid In solution phase and their ratio at the eutectic melting temperature (72 °C) have also been measured with radial heat flow apparatus and Bridgman-type growth apparatus. © IOP Publishing Ltd.
