Abstract

The equilibrated grain boundary groove shapes for a solid Sn in equilibrium with a Sn-Ag-Zn eutectic liquid were observed in a linear temperature gradient by using a Bridgman type directional solidification apparatus. The Gibbs-Thomson coefficient, solid-liquid interfacial energy and grain boundary energy for a solid Sn in equilibrium with a Sn-Ag-Zn eutectic liquid were determined to be (8.21 ± 0.7) × 10-8 Km, (116.2 ± 15.1) × 10-3 J m-2 and (228.1 ± 34.2) × 10 -3 J m-2, respectively from observed grain boundary groove shapes. A comparison of present results with the previous experimental and theoretical results for similar solids in equilibrium with the different liquid was also made. © 2011 Elsevier B.V.
