В исходном состоянии углерод в основном содержится в частицах цементита. После эксплуатации рельсов местом расположения углерода, наряду с цементитом, являются дефекты кристаллической структуры стали. Показано, что процессы перераспределения углерода наиболее интенсивно происходят в поверхностных слоях до 2 мм. Увеличение пропущенного тоннажа сопровождается заметным перемещением углерода на дефекты структуры рабочей выкружки по сравнению с поверхностью катания.</p></abstract><trans-abstract xml:lang="en"><p>The article considers quantitative estimation of the relative carbon content in the structure elements of rail head after passed tonnage of 1411 and 1770 mln tons. In the initial state carbon is mainly located in cementite particles and after the operation the defects of crystal structure together with cementite are the places of carbon location. It is shown that the processes of carbon redistribution take place more intensive in surface layers up to 2 mm. Increase in passed tonnage is accompanied by intensive carbon movement on the defects of working fillet structure compared to the tread surface.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>атомы углерода</kwd><kwd>перераспределение</kwd><kwd>рельсы</kwd><kwd>длительная эксплуатация</kwd><kwd>дефекты</kwd><kwd>цементит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>carbon atoms</kwd><kwd>redistribution</kwd><kwd>rails</kwd><kwd>long­term operation</kwd><kwd>defects</kwd><kwd>cementite</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Выражаем благодарность Е.В.
