Popis:	It has been shown that the theoretical treatment developed by Di Prinzio et al. to study the grain boundary diffusivity in anisotropic material can be experimentally implemented. The method was applied to ice bicrystalline samples. The results obtained show that the diffusivity of tilt boundaries 〈1010〉/21 ° and 〈1010〉/90 ° depends on the grain boundary inclination. As a rule, the authors suggest that when Sun and Bauer's method is followed to study grain boundary migration b and F(α) may always be determined; it should be kept in mind that, neither values of the Mγ(β) function nor the mean value of Mγ were obtained; instead Mγeff was found.
