Abstract
EN: Abstract. The manufacture of rolling stock components with a given life cycle based on the
computerization of all design and production stages is the most promising way to increase the energy
efficiency of its operation. The implementation of this approach requires the expansion of the use of
technologies that provide parts with a high level of mechanical and operational properties. The state of the
surface layers is important in the formation of the reliability parameters of high-loaded parts. The
principles of using system approaches for the physical justification of the choice of the optimal modes of
engineering grain boundaries depending on the operating conditions of products are presented. New
approaches and algorithms have been created that allow quantitative and qualitative studies of the effect of
technological treatments and the chemical composition of polycrystals on the strength of grain boundaries
and the processes of softening of the boundary zones. Using the developed techniques, the ways to control
the energy state of the internal interfaces by doping, microalloying and heat treatment were determined to
increase the resistance to brittle fracture and wear of the steels used in the manufacture and repair of
rolling stock.
