Özet

The equilibrated grain boundary groove shapes for solid Zn in equilibrium with the ZnMg eutectic liquid were observed on rapidly quenched samples. The Gibbs-Thomson coefficient for the solid Zn has been determined to be (10.64 +/- 0.43) x 10(-8) K m from the observed grain boundary groove shapes with the present numerical model, and the solid-liquid interfacial energy for the solid Zn in equilibrium with the ZnMg eutectic liquid has been obtained to be (89.16 +/- 8.02) x 10(-3) J m(-2) from the Gibbs-Thomson equation. The grain boundary energy for the solid Zn has also been calculated to be (172.97 +/- 20.76) x 10(-3) J m(-2) from the observed grain boundary groove shapes.
