Brief historical background about the unit
The Laboratory of Composite Materials was organized in 1985, in the first year of the formation of the Institute of Physics and Mathematics of the Siberian Branch of the Russian Academy of Sciences. The laboratory has its own technological base and metal-working equipment for the manufacture and processing of samples of original materials when conducting research. The laboratory works in close cooperation with a number of universities of the Russian Federation and institutes of the SB RAS, universities and academic institutes of the Republic of Belarus, academic and industrial institutes of the People's Republic of China.

The most important scientific results
1. The patterns of formation of the grain structure of the intermetallic compound Ni 3 Al and an alloy based on it were studied and established under conditions of a volumetric exothermic reaction of the formation of the compound in a powder mixture of initial elements under pressure with simultaneous plastic deformation of the product of high-temperature synthesis, which determine the mechanism of formation of a bimodal grain structure containing high the proportion of nanostructured multigrains, and increasing the strength properties of the intermetallic compound and alloy based on it in a wide temperature range.
2. The patterns of formation of high-strength nano-sized structures in the surface layers of metal-ceramic materials under pulsed electron irradiation in plasmas of inert gases were studied depending on the atomic mass and ionization energy of the inert gas. It has been established that the choice of plasma-forming gas has a significant impact on the structural-phase state and wear resistance of the surface layer - the maximum wear resistance of the surface layer is achieved when irradiated in xenon plasma. In the case of hard alloys with a high content of ceramic components, nanostructuring of the surface layer under electron irradiation in xenon plasma increases the resistance of metal-ceramic plates when cutting metal by 1.5 times.
3. It has been established that during the deformation of ultrafine-grained metals with an fcc lattice in the temperature range 0.2 - 0.4 from the melting temperature, a significant contribution to the overall deformation is made by mechanisms controlled by grain-boundary diffusion. The contribution of grain boundary sliding to the total deformation of these materials in local areas reaches 70%. The low value of the rate sensitivity index and the limited amount of deformation before failure with a significant contribution of grain-boundary sliding to the overall deformation during tension are associated with the heterogeneity of the ultrafine-grained structure, which manifests itself at the mesoscale level.
4. A technique has been developed for producing ultrafine-grained composite materials “metal matrix - ceramic nanoparticles” by the method of repeated rolling with conjugation of layers. It has been shown that the introduction of ceramic nanoparticles into a metal matrix during repeated rolling with conjugation of layers leads to the activation of dynamic recrystallization, as a result of which the structure, texture and mechanism of destruction of the material significantly changes.
5. New approaches have been developed and implemented in modifying the weld pool when applying coatings using surfacing methods, based on the use of highly dispersed (submicrocrystalline) particles of chromium nitride and titanium nitride in combination with a pulsed change in the energy parameters of the technological process in order to form a dispersive grain structure of the coatings. The achievement of the planned result in a wide range of pulsed changes in the energy parameters of the regime has been established.
6. It has been theoretically and experimentally studied and established that increasing the performance indicators of highly loaded products and equipment operating in low climatic temperatures of the Far North and the Arctic is entirely determined by the integrated use of a new generation of welding and surfacing materials, innovative technologies of adaptive pulsed-arc welding and surfacing, as well as methods of special shock-mechanical processing that reduce the level of residual stresses and structural heterogeneity in areas of permanent joints.
Developments
1. A technology has been developed to increase the wear resistance of carbide materials and products made from them by exposure to a pulsed electron beam.
2. Adaptive pulse-arc welding technology has been developed.
3. A modified technology for producing the intermetallic compound Ni3Al by self-propagating high-temperature synthesis has been developed.
