The equilibrated grain boundary groove shapes for the Zn solid solution in equilibrium with the Zn-Al eutectic liquid were observed by rapid quenching. From the observed grain boundary groove shapes, the Gibbs-Thomson coefficient and the solid-liquid interfacial energy for the Zn solid solution in equilibrium with the Zn-Al eutectic liquid have been determined to be (5.80 ± 0.18) × 10 -8 Km and (93.496 ± 7.57) × 10 -3 Jm -2 with the numerical method and from the Gibbs-Thomson equation, respectively. The grain boundary energy for the same material has been calculated to be (182.302 ± 18.23) × 10 -3 Jm -2 from the observed grain boundary groove shapes. The thermal conductivities of the solid and liquid phases for Zn-5 wt pct Al and Zn-0.5 wt pct Al alloys have also been measured.
