description: ". This work is devoted to the study of the kinetics of phase transformations in martensitic-ferritic steels by the dilatometric method and the study of the final structure. To achieve this aim, you must complete the following tasks:
* Perform dilatometric tests with continuous cooling and isothermal exposures;
* Construct and analyze thermokinetic and isothermal curved lines;
* Analyze the structure obtained during the tests.
The work was carried out on the basis of THE FEDERAL STATE UNITARY ENTERPRISE "CENTRAL RESEARCH INSTITUTE OF STRUCTURAL MATERIALS "PROMETEY" NAMED BY I.V. GORYNIN OF NATIONAL RESEARCH CENTER "KURCHATOV INSTITUTE", where a significant part of the actual material was collected: the results of metallographic analysis of metal samples after testing. Dilatometric tests were performed.
As a result, the kinetics of phase transformations was analyzed by constructing thermokinetic and isothermal diagrams of austenite decay. Thanks to the received and developed data, it is possible to adjust the heat treatment of steel products of this grade.
