Abstract: On the basis of generalized RP-model of the nanocrystal, in which there are vacancies in the lattice and the delocalized (diffusing) atoms, the expression for the Helmholtz free energy and the equation of state for the nanocrystal were obtained. The change in the probability of the vacancy formation and the probability of delocalization of an atom, depending on the size and shape of the nanocrystal at different temperatures and pressures were studied. The calculations are performed for BCC iron.

Keywords: vacancies, self-diffusion, nanocrystal, pressure, iron
