Prize-Winners of "Young Scientists" Competition
25.11.2019

Graduate students Artyom Gabov and Nikita Popov, and post-graduate student Roman Minushkin (Department No.9 "Physical Problems of Material Science," INPhE) became prize-winners of the Young Scientists competition held at the International Metal Expo 2019 exhibition.

The aim of the competition is to identify and support talented young people among specialized educational institutions of higher professional education, research institutes, manufacturing enterprises, to encourage their creative skills and to promote results of scientific work to the knowledge-intensive products market.

Artyom Gabov's work "Getting a high-entropy alloy in the system Ni-Nb-Co-Fe-Cr by the method of rapid hardening of the melt for the oxide ceramics adhesion" considers an unusual type of materials – high-entropy alloys. With their use, ceramic soldering compounds of aluminoxic ceramics were obtained. They also allow to study these compounds and analyze the formation of structure in the produced seam.

Nikita Popov's work "Determining the corrosion resistance of soldering compounds from steel 12X18N10T, obtained with nickel soldering" is devoted to solving the urgent problem of nuclear energy, which is the production of thin-walled components of internal devices that are exposed to high pressure, temperature, aggressive environments and radiation during operation. The study analyzed the effect of the temperature-time soldering regime and the chemical composition of the alloy on the structural-phase state of the seam and, accordingly, its corrosion resistance. The possibility of using the developed alloys based on the system Ni-Cr-Si-B and Ni-Cr-P to obtain non-removable lattice compounds from corrosion-resistant steels of the austenite class has been also demonstrated at the exhibition.

Roman Minushkin's work "Changing the structure of surface layers of cylindrical products with the help of combined processing" is devoted to the study of the effect of processing on the change of structure and properties of surface layers of steel shafts and the development of residual macro-voltages in individual sections of shafts modified in different ways. The work was carried out using X-ray methods of studying the surface layers of processed steel shafts. Roman provided a phase analysis and assessment of the structural state of the material after different types of treatment, as well as measured residual macrostrains in all treated areas.
