Özet

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) x 10(-8) Km, (116.2 +/- 15.1) x 10(-3) J m(-2) and (228.1 +/- 34.2) x 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. (C) 2011 Elsevier B.V.
