It is shown that despite the significantly different strength and ductility properties of the steel after the two treatment modes, it is deformed in the yield plateau according to the same Luders mechanism. The mechanism involves emergence and growth of nucleating centers and nuclei of localized strain bands, their intersection at the center of the sample and formation of initiating centers. Tracing of the parameters that determine the initiating stress of the sources emitting dislocations of planar series, which form the growing nucleus of the band, has made it possible to explain the influence of various factors on the top and bottom yield points in the region of the yield drop.

Additionally, technology’s role in accelerating the bainite transformation has been proven. The synergistic effect of carbon atom diffusion and dislocation movement during the pre-martensitic phase transformation process is specifically analyzed. Although the control of multi-phase structures through pre-martensitic phase transformation shows great prospects, some unresolved issues in research still exist.
