| Popis: | WOS: 000255485200008 The interfacial energy of solid bismuth (Bi) in equilibrium with Bi-In eutectic liquid was determined for the equilibrating temperature of 109.5 degrees C. A radial temperature gradient on the sample was established by heating it from the center with a single heating wire and cooling the outside of the sample at -10 degrees C with a heating/refrigerating circulating bath containing an aqueous ethylene glycol solution. The equilibrated grain boundary groove shapes of solid Bi in equilibrium with Bi In eutectic liquid (Bi- 47.3 at.%In) were observed from a sample quenched at 109.5 degrees C. The Gibbs-Thomson coefficient and the solid-liquid interfacial energy of the solid Bi in equilibrium with Bi In eutectic liquid were determined to be (8.4 +/- 0.4) x 10(-8) K in and (54.0 +/- 5.4) x 10(-3) J m(-2) from the observed grain boundary groove shapes. The grain boundary energy of the solid Bi phase was calculated to be (105.5 +/- 11.6) x 10(-3) J m(-2) by considering a force balance at the grain boundary grooves. The thermal conductivities of Bi-47.3 at.%In eutectic liquid phase and the solid Bi-47.3 at.%In phase and their ratio at 109.5 degrees C were measured with a radial heat flow apparatus and a Bridgman type growth apparatus. |
