Abstract

Transmission electron microscopy methods are used to analyze the changes in the structure, phase composition, and dislocation substructure in the head of long differentially hardened special-purpose DT400IK rails made of E90KhAF steel along the radius of fillet rounding at the surface and at a distance of 2 and 10 mm from it after a passed tonnage of 187 mln t during field tests. Bend extinction contours, which indicate an elastic-stressed state of the rail head as a result of long-term operation, are found to form. The sources of lattice curvature torsion are revealed. The mechanisms of destruction of cementite lamellae and repeated precipitation of carbide-phase nanoparticles are considered.
