Measurement of solid-liquid interfacial energy for solid Zn in equilibrium with the ZnMg eutectic liquid

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
