Diffusion growth of two-dimensional precipitates at the grain boundary of a finite thickness was considered with due regard to the diffusion fluxes of impurity atoms from the grain volume to the grain boundary. Stability of the growing precipitates of a relatively small radius was analyzed with respect to the small random perturbations of its size and subject to the surface kinetics of impurity atoms at the grain boundary/precipitate profile. Threshold radii of the precipitates, above which the amplitude of the shape defect and the amplitude of the relative shape deformation of the precipitates rise, were found.
