“…The graph shows that the specialists from Severstal and Magnitogorsk Iron and Steel Works are the leading authors of the patents belonging to these companies. The leading specialists from Severstal P. A. Mishnev, A. M. Korchagin and S. M. Tikhonov had most of their patents and publications in the field of metal processing and rolling [34][35][36][37][38][39][40]. MMK leading specialists (S. V. Denisov and P. A. Stekanov) had inventions also relating to rolling [41][42][43][44].…”

Iron and steel industry is one of the industrial branches making substantial input in provision of economic growth in Russian Federation; in this connection, innovation development of the metallurgical industry is rather important. The patent researches, in their turn, allow to get statistical data about the patents that are indicators of technological development and reliable parameter of innovation activity in the industry. The paper is devoted to study of the tendencies of innovation development of the national vertically integrated mining and metallurgical companies in order to reveal technological and innovation leaders and trends in this industry. The paper uses the patent method of technological prediction based on patent researches. The results of analysis of patent documents for the large metallurgical companies (Severstal, Magnitogorsk Iron and Steel Works (MMK), Novolipetsk Iron and Steel Works (NLMK), Metalloinvest Management Company, EVRAZ Group, Mechel) are presented. The rating of Russian patentee companies — leaders in iron and steel industry — is prepared for the period 2000-2020. The legal status of patent documents included in the patent portfolios of the companies is determined. Patent activity of the companies is analyzed during the examined period with differentiation by years. The patent documents registered in Russia during 20 years, as well as the documents of Nippon Steel and JFE Holdings are also analyzed for comparison. The collection for each patentee was obtained and their interest areas (corresponding to the definite classes of International Patent Classification (IPC)) were examined with revealing of the most important IPC subgroups. Activity of authors of the examined companies is investigated in order to find out the leading technological development specialists.

“…Several solutions have been the subject of numerous research studies to extend its area of application [2]. Among these solutions, modification of the chemical composition by the addition of appropriate alloying elements [3][4][5] and conventional heat treatments [6][7][8] have given the most convincing results. Therefore, most of these parts require heat treatment before starting work.…”

The present work is a contribution in investigating the effect of heat treatment on microstructure, hardness and friction wear of A105N steel. Samples of 25x25 mm2 cross-section and 15mm thickness have been prepared from the as-received material and then heat-treated. The samples were austenitized at 1050°C for 60 minutes followed by water quenching, then tempered at 500 and 700°C for 120 minutes. Microstructural changes and their effect on the wear resistance and hardness were investigated according to the applied heat treatments. The main results show that after quenching the structure is mostly composed of quenched martensite, which confers high hardness and friction resistance to the steel. While the tempered structure is composed of tempered martensite and ferrite. As the temperature rises to 700°C, the tempered martensite decreases and is fully transformed to ferrite and cementite. A good wear resistance expressed by a low friction coefficient and a low wear rate is achieved by tempering at 500°C.
