Andrey Oksogoev at the Institute of High Technologies (Ulan-Ude) has carried out an experiment that proves assumptions made earlier. Research of S.P. Kurdumov’s school dealt with energy division into thermal and nonthermal components upon changes in the environment structure. This possibility is the most important objective for establishing self-organizing nanotechnologies.

A.A. Oksogoev carried out a numerical experiment on deformative analysis of metallic material collision with grit at threshold temperatures. The study of obtained outcomes enabled to single out a special mode called an intensification mode connected with heat inertia effect. Thus, the work done confirms the heat inertia effect predicted earlier and apparent in heat-conducting environments.

The intensification mode concept may become the basis for creating self-controlled (extreme) nanotechnologies. It will make possible to control metallic material properties during their synthesis, face-hardening processing and functioning of materials in a finished engineering construction.

The conducted investigation proves that when additional heat arrives in the environment, the heat does not spread but concentrates in a certain volume for some time. The computing experiment allowed to detect and to demonstrate manifestation of heat inertia effect with the intensification mode in the near-surface layer of the cup central zone in collision crater, as well as to study dynamics of temperature field front profile distribution at the point of grit recoil. To study the thermodeformative state of the near-surface barrier layer, the researchers used aluminium alloy type AVT-1, 8 mm thick, in the course of its high-speed interaction with the ShKh15 steel grit, Ø 4.0 mm.

Heat inertia effect becomes apparent upon increased energy «pumping» into the environment, heat dissipation (conversion of other types of energy into heat) does not spread for some time. The obtained heat concentrates in a certain existing volume. This system status accounts for transition from linear heat conductivity to non-linear one. This results in self-organization of structures that adapt the system to its new existence conditions.

Nanotechnologies development is directly connected with synergetics principle observance, which is the self-organizing systems theory. As follows from the above principles, to obtain considerable results, it is necessary to ensure conditions that meet the fullest adaptation of self-organizing structures to external action.

The distinction of traditional nanotechnologies from self-organizing ones is based on differences in the nature of energy sources that ensure environment structure changes. In the first case, environment structuring occurs at the expense of nonthermal (cold) part of released energy that ensures self-organization processes. In the second case, this happens owing to dissipation (conversion of other types of energy into heat) with the help of energy obtained by the system from environment.
