Abstract: 
There are formulated the key systems of equation describing structurally nonhomogeneous two-component solid solutions. As the key functions there are chosen the stress tensor (displacement vector) and the densities of admixture and skeleton. On this basis the near-surface nonhomogeneity densities of skeleton and admixture, stresses and size effects of surface tension and intensity of the power load causing the thin film fracture are studied. The attention is paid to the admixture influence on size effects.
