Bevz V. Electromagnetic effects and mass transfer in metals under the conditions of the shock loading

Dissertation is devoted to study of the mass-transfer processes and electromagnetic phenomena in metals at the terms of the shock loadings. In the dissertation work is presented the results of parallel re-searches of mass-transfer process and electric impulse formation of current during speed deformation (10-10^3c^-1) of metals. Researches are carried out on metals (Fe, Ni, Cu) and steell (steel 3, 12X18H10T) with the using the isotope-tracers method. The method of electromagnetic signals registra-tion during the impulsive shock loading is developed. It is experimentally set that at the shock loading with the plastic deformation speed of metals arises up impulse of current, in default of outsourcing. The magnitude of effect, for different metals, makes the order of 10-0,5 mV. For explanation of the got results in the work is suggested the model of electric potential appearing in metals and the possible mechanism of process of speed-up mass-transfer is considered at the terms of speed deformation. In accordance with the offered model, shown out dependence for appearing current from speed of deformation, as a quadratic function.
