FORMATION OF COLD RESISTANCE OF K60 STEEL UNDER THE INFLUENCE OF TEMPERATURE AT THE END OF THE ROLLING FINISHING STAGE IN THE INTERCRITICAL TEMPERATURE RANGE
The influence of the intercritical temperature range and the temperature of the end of rolling on the cold resistance of K60 steel, depending on the mechanism of the eutectoid reaction, is investigated. The dependences between the temperature of the critical points Ас1, Ас3, the intercritical temperature interval and the cold resistance are established. A change in the amount of the viscous component was found with an increase in the range of the intercritical temperature interval and the temperature of the critical points Ac3 and Aс1 by 1 ºС. The influence of carbon in the temperature range of existence -iron and peritectic reaction on the transformation of the two-phase area is shown. The effect of the mechanism of atomic hydrogen molization on the ferrite/cementite interface during the first eutectoid reaction on low-temperature viscosity is considered.
