摘要：

The two-dimensional equilibrated grain boundary grooves (GBG) of succinonitrile (SCN) was directly observed by using a temperature gradient stage with high temperature stability to measure the solid-liquid interfacial free energy and its anisotropic factor. Based on the numerical solution of Gibbs-Thomson equation and parameter optimization method, the liquid-solid interfacial free energy and its anisotropy of SCN were extracted from the digitised GBG shapes respectively. The results show that the average solid-liquid interfacial free energy is gamma(0)=9.66x10(-3)J.m(-2), and the average anisotropic factor is epsilon(4)=0.85%.
