INCREASING THE STRENGTH OF RAILS AND THEIR RELIABILITY IN SERVICE ON THE RAILWAYS OF THE USSR

The main measures are aimed at increase of the rail strength. Partly the rail strength increase is attained by means of raising the carbon content is steel, improvement of its metallurgical quality and by addition of alloying elements. The drastic improvement of the rail strength is being attained through the heat-treatment. This article comprises also a short review of the investigation of mechanical properties of hardened rails and their performance after 4-year service. The strength is noted to be considerably increased, the contact-fatigue damage reduced greatly and the general durability raised. Authors give also the method of recovering the hardness of the metal in the zone of welded joints in cwr.
