Abstract
In this paper, we study the effect of cryogenic treatment on the microstructure and properties of high-strength D6AC steel with a bainite and martensite structure. The transformations occurring in steel during heat treatment above and below 0°C was dilatometrically studied. Cryogenic treatment in liquid nitrogen is shown to lead to almost complete restoration of the sample size, which indicates a decrease in the fraction of retained austenite in the structure. This is confirmed by the results of X-ray diffraction analysis. Cryogenic treatment is established to lead to increasing the strength properties and reducing the ductility of D6AC steel.
期刊介绍：
Steel in Translation is a journal that represents a selection of translated articles from two Russian metallurgical journals: Stal’ and Izvestiya Vysshikh Uchebnykh Zavedenii. Chernaya Metallurgiya . Steel in Translation covers new developments in blast furnaces, steelmaking, rolled products, tubes, and metal manufacturing as well as unconventional methods of metallurgy and conservation of resources. Papers in materials science and relevant commercial applications make up a considerable portion of the journal’s contents. There is an emphasis on metal quality and cost effectiveness of metal production and treatment.
