Abstract

The results of quantum-chemical calculations of the properties of five-component alloy TiVZrNbMo in terms of a cluster model are presented. The calculations were performed by Gaussian"03 program within density functional theory at the B3LYP/STO-3G theoretical level. It is established that a simple 15-atom cluster model of bcc metals correctly describes the trends in volume and thermo-chemical properties of 3d- and 4d-transition metals. Estimates of thermochemical characteristics suggest that the relaxed clusters of multi-component alloys are stable and their formation is energetically favorable.
