Computer simulation of atomic structure of rhenium-based amorphous alloys

Using the molecular dynamics method, we constructed the computer models of Re100-xTbx (x=13-89 at. %) amorphous alloys. The statistical geometry analysis of the structure on the basis of Voronoi polyhedra was conducted. We calculated the topological characteristics of the Voronoi polyhedra constructed around Re and Tb atoms and studied their dependence on the composition of the alloys.
