Resumen
STOLER, D.; DRUETTA, E.; PEREYRA, R. y DI PRINZIO, C.L.. Effect of inclination on pure ice grain boundary relative energy. An. AFA [online]. 2017, vol.28, n.4, pp.93-98. ISSN 0327-358X.
In this paper the grain boundary (GB) relative energy γbg/γ s has been measured (γbg GB energy and γ s free surface energy) in pure ice bicrystalline sample with crystal disorientation <0001>/10º . The bicrystal has been studied at -18 ºC and the GB presented different inclinations. The γbg/γ s values were determined from a crystal surface plastic replica using a confocal microscope. The values ofγbg/γ sof bicrystalline sample with crystal disorientations <10-10>/60º and <10-10>/45º have been added in this work. The data ofγbg/γ sare compared between themselves and related with the CSL model for Ih ice. A marked correlation between the CSL and the GB energy has been found.
