The theory of lattice defects as sources of elastic singularities, as extended to non-local elasticity, was used to calculate the interaction energy and force between point defects and dislocations in a special quasi-continuum. It was shown that the interaction energies and forces, that were due to the size effect of the alloying atoms and to the modulus effect of the vacancies, remained finite. This was contrasted with the results of classical calculations, where the distance between point defects and dislocations tended towards zero. A definite binding energy between point defects and dislocations was identified.
