“…The railway wheel is an important structural element of rolling stock. Reliability increases in the operation of railway wheels can be achieved by increasing the property complex of metal by alloying or using heat treatment technologies [1,2]. A disc with the smallest thickness is subjected to complex loads during the wheel operation.…”

Structure and properties of the steel railway wheel disc after forced cooling.Summary. The technological use of accelerated cooling makes it possible to improve the carbon steel properties of the all-rolled railway wheel disc. The properties' complex depends on the temperature of the accelerated cooling termination. This is determined by the ratio of the carbon atoms emitted from the supersaturated solid solution to the crystal structure defects and dispersion strengthening from carbide phase particles. If the cooling stops at a temperature above 350°C, the decline rate of the strength properties increases. This is caused by the excessive softening effect of the solid solution breakdown and cementite spheroidization during the processes of dispersion hardening.

“…Так, у більшості випадків при інтенсивному гальмуванні в тонкому приповерхневому шарі металу ободу колеса температура може дуже швидко збільшуватися до значень, яких достатньо для початку розвитку процесів фазових перетворень [2]. Після закінчення гальмівного процесу, в залежності від швидкості охолодження металу колеса, відбуваються процеси структурних перетворень за різними механізмами.…”
