Abstract

Two first principle schemes were developed for obtaining pair potentials of interatomic interactions for molecular dynamics calculations. The substantiation of the use of pair potentials to the refractory carbides is given. Approved potentials are used for the calculation the cohesive energy and the surface energy depending on the size of the nanoparticles.
