Abstract

Изобретения относятся к металлургии и, в частности, к термической обработке изделий из сплавов на основе железа с содержанием углерода до 4,3 мас.%. Заявляемые способы направлены на сокращение сроков осуществления технологических процессов, обеспечивающих получение изделий из сплавов на основе железа с заданными структурными состояниями. Указанный результат достигается тем, что первый способ термической обработки изделий из сплавов на основе железа с содержанием углерода до 4,3 мас.% включает нагрев, обеспечивающий формирование аустенита и последующее охлаждение по режимам, обеспечивающим формирование заданного структурного состояния, при этом охлаждение осуществляют по режимам, обеспечивающим наличие областей аустенита с химическим составом, близким к эвтектоидному, с последующим получением в них маринита, а заданное структурное состояние формируют с получением в нем перлита различной степени дисперсности и/или закалочных структур. Указанный результат достигается тем, что второй способ термической обработки изделий из сплавов на основе железа с содержанием углерода до 4,3 мас.% включает нагрев и последующее охлаждение по режимам, обеспечивающим формирование заданного структурного состояния, при этом нагрев осуществляют по режимам, обеспечивающим формирование маринита, а заданное структурное состояние формируют с получением в нем перлита различной степени дисперсности и/или закалочных структур. При реализации способов используют импульсное охлаждение, пластическую деформацию и воздействие магнитного поля.The inventions relate to metallurgy and, in particular, to heat treatment of articles made of iron-based alloys with a carbon content of up to 4.3 wt.%. The inventive methods are aimed at reducing the timing of technological processes, ensuring the production of products from iron-based alloys with given structural states. This result is achieved by the fact that the first method of heat treatment of articles made of iron-based alloys with a carbon content of up to 4.3 wt% includes heating, which ensures the formation of austenite and subsequent cooling according to modes that ensure the formation of a given structural state, while cooling is carried out according to modes , providing the presence of regions of austenite with a chemical composition close to eutectoid, followed by obtaining marinite in them, and a given structural state is formed with obtaining pearlite of various degrees of dispersion and / or quenching structures in it. This result is achieved by the fact that the second method of heat treatment of articles made of iron-based alloys with a carbon content of up to 4.3 wt% includes heating and subsequent cooling according to modes that ensure the formation of a given structural state, while heating is carried out according to modes that ensure the formation of marinite , and a given structural state is formed to obtain pearlite of various degrees of dispersion and / or quenching structures in it. When implementing the methods, impulse cooling, plastic deformation and exposure to a magnetic field are used.
