Abstract

We have proposed a mechanism according to which interstitial atoms appear in the crystal lattice as a result of compressive strains. This occurs, when the relative volume strain exceeds a certain critical value. The equilibrium concentration of interstitial atoms appearing due to the proposed mechanism is calculated. A characteristic feature of this effect is the rapid, at the sound velocity, establishment of the indicated concentration over the crystal volume.
