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) x 10(-7) K m and (40.4 +/- 4.0) x 10(-3) J m(-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) x 10(-3) J m(-2) by considering force balance at the grain boundary grooves. The thermal conductivities of the In-12.4 at.% Bi eutectic liquid phase and the solid In solution phase and their ratio at the eutectic melting temperature (72 degrees C) have also been measured with radial heat flow apparatus and Bridgman-type growth apparatus.
