PRODUCTION OF NEW GENERATION RAIL STEEL
Keywords:rail steels, bainite, smelting, rail, chemical composition
Based on research in recent years, it is known that the strength of pearlitic rail steels has reached the limit. Therefore, there is an urgent need for other alternative materials. Bainitic steel, which provides both high strength and excellent ductility, is considered one of the most promising areas. To fulfill this task, four variants of experimental steels were developed. Ingots with different alloying systems were manufactured in the laboratory conditions of the ISI NASU. Studies of the influence of cooling rate, temperature and cooling duration on the formation of the microstructure of experimental steels have been carried out.
