Vibrations of atoms or ions around the lattice points are inhamonic that cause the thermodynamic effects for the materials with the crystal structure. Using in the stastical physics, within the fourth order moment approximation, we have found out that the change of the length, volume and shape of the metallic superlattice are determined by the anharmonic effect. Increasing temperature leads to the more strong anharmonic lattice vibrations that cause changing size of the material.
