The objects of research are composite discrete-reinforced and dispersion-strengthened high-temperature materials and coatings.
“In situ Diagnostics of Structural Transformations” Laboratory was established by Order No. 177d o.v. dated 18.06.2020 for the state task by the Ministry of Science and Higher Education of the Russian Federation under the project 0718-2020-0034 “Development of hierarchically structured discrete-reinforced and dispersion-strengthened thermal stable materials for heat loaded nodes of advanced space rocket hardware” (theme 3164024).
The laboratory is a part of the Scientific and Training Center of Self-Propagating High-Temperature Synthesis of MISIS and the Institute of Structured Macrokinetics and Issues of Materials Science of the Russian Academy of Sciences and carries out research in cooperation with the Federal State Institution Federal Research Center “Crystallography and Photonics” RAS, using modern methods of transmission electron microscopy.
Main fields of scientific activities of the laboratory
Fundamental studies of the dynamics of structural transformations during deformation and heating of multicomponent composite materials and coatings produced by self-propagating high temperature synthesis, as well as studies of powder metallurgy, selective laser alloying, ion-plasma deposition and electrospark alloying.
Priority groups of materials include:
- dispersion-strengthened heat resistant alloys based on nickel and titanium aluminides, ultra-high-temperature composites (UHTCM), hard alloys;
- discrete reinforced composite materials with ceramic and metal matrix;
- heat-resistant and heat-stable coatings.
Solubility boundaries of solid solutions, deformation mechanisms in a wide temperature range, temperature-time conditions of aging are being researched. The influence of excess phases on properties and high-temperature creep of alloys is studied. The mechanisms of high-temperature oxidation and the effect of composition/structure on the thermal stability of materials are also being researched.
