Based on an analysis of stepwise deformation and acoustic emission data, a conclusion is made concerning the active role of acoustic emission in activation and, above all – in synchronization of elementary events of deformation on a macroscopic scale. The macroscopic scale is controlled by the wave nature of synchronization of the elementary deformation events in the stress field, which form a low-stability state of the crystal lattice of a deformed material. The principal role belongs to interference of the acoustic signal wave packages, resulting in macroscopic distribution of critical vibrational displacements in a low-stability crystal medium.
