QUANTITATIVE ASSESSMENT OF THE EFFECTIVENESS OF HARDENING MECHANISMS FOR CARBON AND LOW-ALLOY STEELS WITH DIFFERENT STRUCTURAL STATES

The aim of the work is a quantitative approximate assessment of the contribution of various hardening mechanisms for carbon and low alloy steels according to their chemical composition and parameters of a thin metallographic structure. It is generally accepted that the work is of scientific and practical interest, since, as is known, there is currently no theory that satisfactorily describes hardening mechanisms, especially for new promising hardening methods (combined hardening methods, combined heat treatment methods, plasma, laser processing, etc.). There are only approximations that describe the existing hardening mechanisms, which do not provide a rigorous quantitative assessment of the yield strength of steels with different structural states.
