Abstract:

In this paper discusses and demonstrates the possibility of modeling materials with amorphous and nanocrystalline structure using random close packing of atoms and nanoclusters models. Concordance structure of the real models alloys was evaluated by the radial distribution function obtained as a result of calculations, and in its modeled structures estimation. Modeling structure of the amorphous matrix and the spatial distribution of nanoclusters in two-component amorphous alloys with composition Fe80B20 carried out by Ishikawa method. For modeling structure multicomponent amorphous metal alloys we developed correlation-spectral model of the amorphous matrix and nanoclusters. At modeling passing electron wave through the sample used a layered approach, and for the "visualization" imaging we modeled optical schemes of high-resolution electron microscopes.
