The conditions for obtaining nanostructures (NS) and nano parts hardening and RI. Based on the analysis of experimental data on the conditions for fabricating nanostructures were formed by the criteria of their education: - the presence of temperatures in the range 500-1500 K; - nanostructure growth rate to exceed 10е7 K / s; - thermal stresses should be close or equal to 10е9 N/m2. 2. The theoretical basis for fabricating nanostructures under the flow of ions of different types, energies and charge it possible to find the temperature field and thermal stress. Given the criterion of the formation of the National Assembly received grain size, the amount of nanoclusters, the number of particles in a nanocluster, the rate of increase in the temperature dependence of the energy and charge of the ions, C, N, Al, Ti, V, Cr, Ni, Y, Zr, Nb, Mo , Hf, Ta, W, acting on the steel, which revealed the conditions of formation of the National Assembly on the surface toli toli in the volume of the surface layer, and to evaluate the current density at which the maximum fill volume is the surface layer of nanostructures (70-90%). 3. A model of the flow of electrons of different energies and current density on the steel, where it is shown that the action of the three streams of electrons with different energies of 3.3 keV, 6.6 keV and 9.9 keV and current densities close to the critical first is the possibility of the National Assembly . 4. On the example of the flow of electrons with energies of the three 3.3 keV, 6.6 keV and 9.9 keV and current densities close to the first critical steel layer 50 were from 0.4 to 0.7 mm with a microhardness of about 50GPa, which is not etched, while tempering can not provide hardness of more than 6-7 GPa. All this speaks of the reality of the proposed models and criteria for fabricating nanostructures. Product Description popup.authors Воропай Р.В. Костюк Г.І. Мелкозерова О.М. Павленко В.М.
