Abstract
It has been discovered that grade 30KhGSA steel after a high-temperature thermomechanical treatment is more plastic at −196°C than at room temperature, unlike in the case of quenched steel and uncharacteristically for metals or alloys with a bcc crystal lattice. A study has, therefore, been made to establish the temperature characteristic of the resistance to deformation and, especially, to its reversible component, both after an anneal and after a heat treatment of steel. The activation energy and volume of the thermally induced deformation were measured, whereupon the results were analyzed on the basis of the Payerls mechanism with dislocations frozen by interstitial impurities. No differentiation was made between the behavior of steel after a quench and after a high-temperature thermomechanical treatment, respectively, so that differences in the low-temperature diagrams could be related to the peculiarities of nonthermal deformation and to the resistance to brittle fracture.
