“…After combined deformational processing with drawing with alternative bending and torsion the plate structure of pearlite is broken. As it was shown in [22] the substructure with mixed dislocation-carbide boundaries and some increase in dislocation density which is observed in the crashed form of the pearlite structure after steel cold deformation leads to the resistance of dislocation movement and hence to the increase in strength properties of the processed carbon steel wire [23][24][25].…”

At present time tendencies in the development of engineering and technologies in the manufacturing the metal ware need the effective complex impact on material microstructure by methods of different nature. Special attention should be paid to the combined processes of deformational treatment which are constructed on such basic operations as drawing, rolling, pressing, etc. Despite a plenty of studies and high efficiency of combined methods the problem of understanding the scientific grounds for choice the processing parameters which ensure the guaranteed level and high stability of metals and alloys properties has not been solved jet. Medium carbon steel is used for a wide range of metal ware products. Medium carbon steel wire with 0.5 %C was chosen for the experiments. It was subjected to different kinds of deformational processing such as tensile deformation, alternating bending, twisting and their combination. Complex of experimental research was carried out in order to study the influence of different kinds of plastic deformation on the medium carbon steel wire microstructure. By scanning electron-microscope analysis the peculiarities of pearlite behavior after deformational processing with different total deformation degree were studied. The comparative analysis of cementite changing after different kinds of deformation was conducted.

“…For example, sensors that record the parameters of the execution processes; software and hardware for the implementation of recognition algorithms; local area networks; means and communication systems; automated workplaces of management personnel at various levels of enterprise management, etc. (Chukin et al, 2016b). At various stages of the life cycle of a specialized recognition system, industrial and production personnel, engineering and technical, administrative and managerial in the processes of its design and creation can participate; in the system of collecting the initial information about the recognized elements of the environment; in the analysis (examination) of intermediate and final recognition results; in the learning process of the recognition system, if the recognition system is "with training"; in making decisions on the implementation of recommendations developed by the system of recognition and a number of other works.…”

The factors responsible for the emergence of problematic situations in the company's production, economic, financial and economic activities are the unacceptable controlled disturbances of the external and internal environment of the enterprise and the unacceptable deviations of the actual states of the execution or management processes from the required ones, impeding (creating threats) or contributing (creating potential opportunities) achievement of the established objectives of the functioning and development of the enterprise. The essence of recognition of problem situations is considered and analyzed. A specialized system for recognizing problematic production situations is presented as a complex dynamic automated (automatic) system that realizes in real time the transformation of input information about a problem situation that has arisen in the course of production and economic activity into output information about its belonging to a certain reference class of problem production situations. Examples are given of the use of specialized systems for recognizing problematic production situations in the operational management of production, innovation processes and processes of functional maintenance of production and innovation processes implemented at the enterprise. Named the main tasks solved in the design, creation and operation of specialized systems for recognizing problematic production situations, and the methods used in the course of solving them. The advantages of using specialized systems for recognizing problem situations in the production and economic activities of production systems with intellectual support are indicated.

“…В настоящее время создавать крупногабаритные изделия из наноструктурных материалов не представляется возможным ввиду отсутствия технологии и из-за проблем, связанных со сварными соединениями. Известно, что определенные успехи достигнуты в наноструктурировании стальной проволоки и арматуры [1][2][3][4]. Для многих конструктивных материалов с целью повышения их служебных характеристик более целесообразно осуществлять наноструктурирование поверхностных слоев и нанесение функциональных наноструктурных покрытий [5][6][7][8][9][10][11][12].…”

Рассмотрены наноструктурирующая обработка металлических поверхностей и нанесение функциональных покрытий гибким инструментом-вращающимися проволочными щетками (ВПЩ). Этот процесс, названный фрикционным плакированием, реализуется на токарных, шлифовальных и других металлорежущих станках с использованием простой оснастки или ручных углошлифовальных машин (УШМ). При металлографическом исследовании поверхностных слоев в качестве изучаемых образцов применялись пластины 3×20×100 мм из стали марки 08. Покрытия наносили на плоскошлифовальном станке, на котором размещались ВПЩ вместо абразивного круга и приспособление для подачи материала покрытия. Цилиндрические образцы (сталь марки 50) диаметром 20 мм обрабатывали на токарном станке, на суппорт которого устанавливалось приспособление с УШМ. Для металлографических исследований использовали оптические микроскопы и растровый электронный микроскоп РЭМ JSM-6490 LV. Электронно-микроскопические исследования проводили методом реплик на электронном микроскопе «Tesla BC-613». Рентгеноструктурный анализ выполняли с помощью дифрактомера «Дрон-3». Измерения и анализ шероховатости осуществляли по методике стандарта ГОСТ Р ИСО 25178 на установке «Contour GT K1» (Bruker). Проведено исследование структуры, текстуры и микротопографии поверхности медных и латунных покрытий, нанесенных гибким инструментом на стальную основу. Средняя толщина покрытий составляла 20-25 мкм, микротвердость медного покрытия-около 6800 МПа, латунного-9000 МПа, размеры частиц-в пределах 0,3-0,6 мкм. Кристаллографическая текстура покрытий воспроизводит текстуру материала стальной основы. Изучение микротопографии поверхности образцов до и после нанесения покрытий показало, что латунное покрытие существенно сглаживает поверхность, но исходную микротопографию меняет незначительно. Микротопография медного покрытия существенно отличается от исходной.
