GENERATION OF NI44NB56 AND NI62NB38 METALLIC-GLASS COMPUTER-MODELS AND INVESTIGATION OF THEIR STRUCTURES

Computer models of Ni44Nb56 and Ni62Nb38 metallic glasses were generat ed using the original iterative procedure based on the molecular dynam ics method and the Born-Green-Bogoljubov equation (without use of the superposition approximation). Analysis of the first neighbor shells, l arge cavities and Voronoy polyhedra distributions was performed. It wa s found that the structure of the Ni44Nb56 metallic glass is less orde red and less dense than the structure of the Ni62Nb38 metallic glass.
