The results of a theoretical analysis of the elastic-stressed state and the distribution of elastic energy in nano structured metallic materials in the vicinity of nanograin boundaries with a high density of partial disclinations are presented. The features of the distribution of the stress fields of disclinational grain-boundary configurations as a function of the size of nanograins are determined taking into account the superposition of these stresses during the screening of disclination pile-ups. It’s found that the maximum values of the main components of the stress tensor are achieved only in the disclination planes P « Ef 25, and the gradients of these stresses are characterized by the maximum values at the nodal points dP/dx ~ 0,08 E nm'‘. It’s shown that the local energy maxima are a characteristic feature of the distribution of the specific elastic energy of these configurations, which can be the cause of the physical broadening of the nanograin boundaries.
