Effect of Long-Term Operation on Structural-Phase State of Hypereutectoid Rail Steel

Abstract—For rails of increased wear resistance and contact endurance of the DH400RK category made of E–0.9C–Cr–V–Fe hypereutectoid steel, after a tonnage of 187 million tons, the fine structure in the railhead along the central axis at distances of 0, 2, and 10 mm was analyzed using transmission electron microscopy for the four morphological components of pearlite from the rolling surface. The nonmonotonic change in scalar and excess dislocation density, fragment size, cementite particles, and internal long-range stress fields in the railhead section was analyzed.

期刊介绍： Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
