Resumen
LADO, M; STOLER, D; AGUIRRE VARELA, G y DI PRINZIO, C. L. Study of the evolution of grain boundary profile on the surface of ice by evapo-diffusive processes. An. AFA [online]. 2019, vol.30, n.1, pp.10-13. ISSN 0327-358X.
In this work, we studied the evolution of the groove that forms the grain boundary (BG) when it emerges to a free surface, in the presence of different processes of matter transport. The depth of a groove of the BG was obtained in an ice sample with orientation <1010>/50° at -5 ºC for 3 h in dry air, by using a confocal microscope. The experimental results are fitted correctly with a process of transport of matter governed mainly by gaseous diffusion.
