Abstract
Metallographic examination of a rail of R65 type produced in Japan has been conducted after its use in the East-Siberian Railway has been conducted. It has been shown that, as for the chemical composition, the metal sample meets the requirements of the specifications of TU 0921-239-01124323 – 2007 specified for steel for production of rails 350LTD. Metal macrostructure quality is satisfactory. Tensile properties, cross-section hardness, and impact strength at temperature +20 °С determined in the samples cut out from the rail head rounding-out having no contact with the wheel meet the requirements of the specifications of TU 0921-239-01124323 – 2007 for rails 350LTD. However, impact strength at sub-zero temperatures does not comply with the quality of domestic rails for low-temperature service. Nonmetallic inclusion content is not significant, however unallowable inclusions of exogenous nature have been found. The microstructure of the sample of rail produced in Japan is sorbitic and lamellar pearlite, which dispersity decreases with the increase of the distance from the surface in all elements of rail samples. When in service, slanting line cracks to 1.1 mm in depth were located on the surface of the rail head rounding-out having contact with the wheel and also considerable side wear ammounted up to 15 mm.
