The equilibrated grain boundary groove shapes of solid In2Bi solution in equilibrium with the In-Bi-Sn eutectic liquid were observed from a quenched sample at 59°C. The Gibbs-Thomson coefficient, solid-liquid interfacial energy and grain boundary energy of the solid In2Bi solution have been determined to be (1.42 0.07) × 10-7 K m, (49.6 5.0) × 10-3 J m-2 and (97.1 10.7) × 10-3 J m-2, respectively, from the observed grain boundary groove shapes. The thermal conductivities of the solid phases for In-21.23 at% Bi-19.04 at% Sn and In-30.5 at% Bi-3 at% Sn alloys and the thermal conductivity ratio of the liquid phase to the solid phase for In-21.23 at% Bi-19.04 at% Sn have also been measured with a radial heat flow apparatus and a Bridgman type growth apparatus, respectively, at their melting temperature. © 2008 IOP Publishing Ltd.
