AbstractThe post-irradiation recovery annealing of grade 14Kh17N2 steel used in the intermediate control bayonets of WWER reactors is optimized. It is shown that the proposed heat treatment conditions completely recover the mechanical properties of the bayonet metal embrittled under neutron irradiation. That said, the chosen conditions do not reduc...

AbstractThe paper presents the results of a study of the relationship between strength and performance (ductile–brittle transition temperatures Tdb and zero plasticity NDT, critical opening at the crack tip CTOD at a test temperature of –40°C) on the structural parameters of hot-rolled plate made of low-carbon low-alloy steels with different conten...

The use of local brittle fracture criteria for predicting the crack resistance of low-alloy steels is a generally accepted approach. The feasibility of this approach is analyzed as applied to the experimental smelts of high-strength low-alloy steel plates with yield strength amounting to about 1000 MPa, whose structural was studied earlier. Three t...

The results of the study of experimental carbon fiber reinforced plastics based on a thermoreactive PMR polyimide binder are presented. The studies of the thermal stability of the carbon fiber reinforced plastics are carried out and their elastic strength characteristics at temperatures up to 320°C are determined. The possibility in principle of pr...

The results of laboratory and bench tests of UGET and FUT antifriction carbon plastics macromodified with polytetrafluoroethylene (PTFE) are presented. The efficiency (reduction in the friction coefficient) of such modification of carbon plastics has been confirmed. The dependence of the efficiency of this method on the design of sliding friction u...

This work analyzes the structural integrity and brittle fracture resistance of the intermediate control bayonets of the control and protection system (CPS) of the WWER-440 reactor. The tests of the metal of the bayonets irradiated as part of Novovoronezg NPP unit 3 show that the structural integrity of the bayonets against the brittle fracture crit...

AbstractIn this paper, we studied the kinetics of austenite grain growth during heating and the processes of dynamic and static recrystallization occurring in various modes of plastic deformation (reduction pattern, deformation temperature) of high-strength steels with various microalloying complexes. The performed studies allowed determining the t...

AbstractA quantitative comparative analysis of the strengthening mechanisms for the surface layers of rails is carried out. It is based on the regularities in forming structure, phase composition, defective substructure, and properties of differentially hardened 100-m rails at different depths (up to 10 mm) and performed in the rail head along the ...
