Abstract

The equilibrated grain boundary groove shapes for solid Sn in equilibrium with the (Sn-3.84 at.% Ag) eutectic liquid were observed from a quenched sample at the eutectic temperature for about 18 days with a radial heat flow apparatus. This is the first time that the equilibrated grain boundary groove shapes of solid Sn in equilibrium with the (Sn-3.84 at.% Ag) eutectic liquid have been observed using radial heat flow apparatus. From the observed grain boundary groove shapes, the Gibbs-Thomson coefficient, the solid-liquid interfacial energy and grain boundary energy for solid Sn in equilibrium with the (Sn-3.84 at% Ag) eutectic liquid were determined to be (8.54+/-0.42) x 10(-8)Km, (113.32+/-11.33) mJ/m(2) and (216.11+/-23.77) mJ/m(2), respectively.
