Purpose of work - to give recommendation in relation to the choice of the rational modes of heat treatment, and also composition of steels, for providing of optimum complex of mechani-cal and operating properties. Research methods - metallographic, X-ray diffraction, dyurometrical; test on an dry fric-tion; the statistical processing of results. The combined heat treatment of steels, which includes with preliminary decomposition of austenite to the FCC and the further hardening, provides grain refinement and obtaining metasta-ble austenite reinforced with dispersed carbides, contributes significantly to wear under dry fric-tion than steel 110Г13Л through quite intensive - transformation during operation. It was established and experimentally confirmed that TCТ can be regarded as an effective tool for removing hydrogen from the steel and improve their mechanical and service properties. The proposed quantitative characterization of the degree of heterogeneity of the space-governmental distribution of chemical elements in steel. The possibility of the forming com-pletely homogeneous distribution of the concentrations of chemical elements in welded microal-loyed steel after isothermal holding different durations at subcritical temperatures. Industry of the use - machine-building and metallurgical enterprises of Ukraine. Product Description popup.authors Іващенко Вікторія Юріївна Бурова Д.В.
