The research materials on the basis of a titanium and nickel (alloys BT3, BT8), single crystal niobium samples were used. The experimental technique of activity bases on a X-ray diffractometry, measurements of distribution of a work function of electrons on a surface, tests for a kinetic dimpling. For the analysis of electric pulse effect on metals the flowchart and MD program of simulation is performed. For the analysis of changes of physical-mechanical properties of surface layers of metals, the way of a kinetic dimpling is designed on the basis of measurement of a contact resistance.It is showed, that the measurement of time, load and resistance during an intrusion spherical indenter in a stuff, allows to determine the basic mechanical characteristics of near-surface layers: a modulus of elasticity, yield strength, activation volume. The residual stresses of the I- and II- kind before electric pulseprocessing are gauged. The improvement plainly states of stress of a stuff of a near-surface layer after electric pulse processing is revealed. Designed during activity a technique of a kinetic dimpling the way of X-ray difractometry of definition of elastic modules, electric pulse processing can be utilized in mechanical engineering area by optimization of surface hardening processing.
