“…For most carbon steels with ferritic-pearlitic structure, 0; "' 70-90 MPa [3,5,6]. Therefore, the obtained value 0; "" 100 MPa is in satisfactory agreement with the literature data and confirms the fact that the supersaturation of ferrite of the pearlitic colony with carbon atoms does not affect the strength of steel after thermomechanical treatment.…”

It is shown that the intense cooling (with rates of 2-9°C/sec) of wheel rims after their hot rolling in a rolling mill increases the yield limit and the ultimate strength of the metal. It is also established that, in the absence of supersaturation of the solid solution with carbon atoms in the course of this kind of cooling, the mechanical properties of carbon steel are determined solely by the internal stresses caused by the phase hardening of ferrite in pearlite and the state of ferrite-cementite boundaries.

“…As the latter can be attributed to arise from interactions among dislocations, its fluctuations in the 10-13% strain range indicate a correlated variation of the work hardening mechanism as a result of a change in the slip mode (34,37,38). The slip mode would change from the movement of single dislocations, within the grains, to the one resulting from the cooperative movement of dislocations in the cell walls.…”

“…The lattice friction stress, 0, may vary by up to 4.5 times, mainly due to the presence of solid solution strengthening elements (in particular free carbon), and was reported being in the range of 15 -70 MPa [10,[50][51][52][53]. The grain size strengthening coefficient, k, insignificantly (up to 9 %) varies with steel composition, temperature and strain rate, and was reported being in the range of 21.4 -23.5…”
