Abstract

The purpose of the study is to clarify the mechanism of interatomic interaction in the model of Ya.I. Frenkel and to link this process with the propagation of ultrasound in the crystal lattice of metals, as well as with the velocity of propagation of ultrasound in rods from different materials taken as standard samples for determining the Yung's modulus. An analysis of the mechanism of interatomic interaction in the diatomic model Ya.I. Frenkel is made. A model that linked the process of interaction of the electron shells of atoms with the speed of sound propagation was created, taking into account the structure of the metal crystal lattice. The new model allows the theoretical calculation of the ultrasound velocity in different crystal lattices of metals. In the result of the research, it was found that the theoretically calculated values of the ultrasound velocities with a sufficiently high accuracy coincided with the experimentally obtained values of its propagation, which makes it possible to correlate the rate indicator with the strength properties of metals.
