Paton Institute of Materials Science and Welding of Igor Sikorsky Kyiv Polytechnic Institute was the organizer of the International Scientific Conference "Materials for work in extreme conditions - 10", which took place at the end of last year. Under quarantine restrictions, the conference was held online.
The organizing committee received 83 reports, 23 of which were viewed during the two days of the conference. Among the authors of the reports are scientists not only from Ukraine, but also from Japan, France and Germany. They worked in the following sections: "Composite reinforced and powder materials", "Multifunctional coatings and surface engineering", "Materials crystallized from melt", "Information support of scientific research in materials science", "Synergetics and computer modelling in materials science and metallurgy", "Nanomaterials and nanotechnologies", "High-entropy alloys", "Modern methods of training specialists for innovative materials science".
The introductory word and the report on a subject "Modern materials for work in extreme conditions" was made by the scientific adviser of Paton Institute of Materials Science and Welding of Igor Sikorsky Kyiv Polytechnic Institute Corresponding Member of the National Academy of Sciences of Ukraine, Doctor of Technical Sciences, Professor Petro Loboda. He stressed that for modern materials in a wide range of temperatures it is necessary to implement a set of unique physical and chemical properties, such as high wear resistance, chemical and corrosion resistance, excellent mechanical properties. Such properties can be realized by creating a nanostructured state in the material and forming various composite materials, such as ceramic composites LaB6-TiB2.
Almost all the reports of the conference highlighted the pressing issues that scientists in many countries are currently working on. Its distinctive feature was the inclusion in the program of the section "High entropy alloys". Among the reports on this topic should be noted the following: "Mass-spectrometric with glow discharge and X-ray fluorescence analysis of high-entropy alloys”( sen. sc. worker IPM NAS of Ukraine, doc.chem.sc. Volodymyr Kurochkin); "Composite materials based on WC-W2C with high-entropy AlNiCoFeCrV bond”(can.tech.sc., ass.prof. Yevhen Solodkyi, Department of High Temperature Materials and Powder Metallurgy); "Phase composition of AlCrMnFeCoNi alloy after long-term oxidation at 900oC" (graduate student Mykola Yakubiv, Department of Metallurgy and Heat Treatment); "The use of models and methods of grain boundary control to improve the performance of improving steels”(can.tech.sc., ass.prof. Oleh Kuzin, Department of Smart Connection Technologies and Surface Engineering).
The master-graduates of the Department of Metallurgy and Heat Treatment also made their reports at the conference, and a week later they defended their diploma projects before the state examination commission. Through the practice of oral presentation to the general scientific community, they gained valuable experience for the successful defense of their first scientific works.
Proceedings of the conference in the form of extended abstracts will soon be published by the university. They can be found at: https://mto.kpi.ua/nauka/konferenczi%D1%97/.
