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 impact-abrasive wear; mathematical processing of results. The combined heat treatment is the effective method of adjusting of stability of austenite in relation to attitude toward deformation martensite transformation, and due to the lowered maintenance of manganese in new steels disintegration of austenite is considerably easier pro-vided with the receipt of ferritic-carbide mixture, than in steel of Gadfil'd. Possibility of grinding down of grain is conditioned these as a result of subsequent recrystallization, that it is extraordi-narily important for the poured details. Preparation of metastable austenite and optimal implementation of the DMT in the process of wear possible to obtain high wear resistance in economically-rated iron compared with a high alloy. The technique of calculation - experimental modeling process cooling large forgings using cyclic cooling of laboratory samples in different cooling environment. Industry of the use - machine-building and metallurgical enterprises of Ukraine. Product Description popup.authors Іващенко Вікторія Юріївна Бакума А.О. Бурова Д.В.
