Features of phase and structural transformations of structural steels under non-traditional modes of heat treatment

It is determined, that during heat treatment of structural steels with heating to an extreme temperature during quenching or normalization, the increase in the density of dislocations in the crystal structure of the α-phase is comparable to the density when heated to a standard temperature (Ac3 + 30÷50 °C), and its change depends on the amount of carbon and chemical alloying elements in steel. Keywords heat treatment, high hardness, dislocation density, extreme temperature, low alloy steel. [email protected].
