DI PRINZIO, C. L.; ACHAVAL, P. I.; STOLER, D.  e  AGUIRRE VARELA, G.. Grain boundary migration in thin films using Monte Carlo method. An. AFA [online]. 2020, vol.31, n.1, pp.07-12. ISSN 0327-358X.

This paper presents the evolution of a flat grain boundary in a thin sample, using a numerical algorithm based on the Monte Carlo method. The grain boundary is driven by an external force and the effect of the free surface is studied. The grain boundary migration on the free surface is spasmodic, which means that it has alternating periods of movement and stagnation. Stagnation periods are inversely proportional to the thickness of the sample. The results obtained computationally fitted acceptable with the theoretical results obtained by different authors.
