Motion of particles through the interface of different-density metal specimens under the conditions of superdeep penetration

The parameters of motion of particles in a thin layer of material adjacent to the plane boundary of two semi-infinite specimens of different densities under the conditions of superdeep penetration are calculated on the basis of the hydrodynamic model. Results of the calculations are checked experimentally. The efficiency of superdeep penetration for different-density materials (aluminum, steel, copper) and their combinations is determined.[PUBLICATION ABSTRACT]
