Özet
The Gibbs-Thomson coefficient and solid-liquid interfacial energy of the solid Mg2Zn11 phase in equilibrium with Zn-Mg eutectic liquid have been determined to be (3.3 +/- 0.2) x 10(-8) K mand (20.8 +/- 2.1) x 10(-3) J m(-2) from the equilibrated grain boundary groove shapes with a numerical model. The grain boundary energy of the solid Mg2Zn11 phase has been calculated to be (40.9 +/- 4.5) x 10(-3) J m(-2) by considering a force balance at the grain boundary grooves. The thermal conductivity ratio of the eutectic Zn-Mg liquid phase to the solid Mg2Zn11 phase has also been found to be 0.81.
