It means that diffusion Zn through growing phase take place with the further reaction on the Cu5Zn8 — Cu interface boundary. The high hydrostatic pressure reduce the growth rate of the phase. A scattering of acoustical phonons from a planar crystal defect is studied. A resonance transmission and reflection of the transverse phonons from the planar defect is discovered and conditions of such a process are investigated. It is shown that the resonance conditions are connected with existence of longitudinal phonons localized at the planar defect and traveling along it. The structure of tracks induced on surfaces of layered crystals by fat heavy ions irradistion were studied by method of electron microscopy. It was established that the direction of the ion path can be decreased every time the ion cross the next densely packed layer if the angle of ion incidence < 1o. When the angle of ion incidence reach a critical value the ion moveparallel to the crystal surface in the channeling regime. This work results may be used for the elaboration of the theory, technology and exploutation of the modern hotstable materials which worked in the conditions of the high hydrostatical presse and at the action of the heavy ions irradiation.
