Abstract


The volume of nanostructures that are realized under the action of a number of ions (boron, nitrogen, zirconium, hafnium) is determined using the example of studying the influence of the fraction of components in a solid alloy containing Al2O3 and TiC at their different ratio of the fraction of components. Conditions (component ratios) are obtained for which the minimum grain sizes are realized, i.e., the hard alloy surface has the best physical-mechanical characteristics at 50Al2O3 and 50TiC. It is shown that when processing pure Al2O3 and TiC, it is also possible to obtain rather low grain size values. At the ratios of components 20-80 and 80-20, larger grain sizes are realized than in the previous cases. Nonequilibrium states can also be used after studying the physical and mechanical characteristics of hard alloys. It is shown that under the action of light ions (nitrogen), the temperature stresses do not reach the necessary values for the formation of nanostructures, and under the action of heavy ions (hafnium) there is a high probability of realization of nanostructures at an energy of 20 keV and insignificant under the action of ions with an energy of 200 eV.
