Abstract
The research focuses on impact of temperature variations on the strength of railway line steel. Railway line steel must be made from a strong material that endures wear, fatigue, or different temperature effects, in order for the railway transport to be able to supply uninterrupted good service to the customers. Tests conducted included the microstructural analysis, chemical composition, and Vickers hardness testing. The results revealed that the temperature that samples were exposed to have an effect on the mechanical properties of the steel. The microstructural analysis showed that the fatigue loading on the steel samples caused grain transformation and dislocated the grain elements. The results revealed that as the temperature increases due to cyclic loading, carbon content decreases, the steel becomes harder, and develops brittleness. This then results in the areas with higher brittleness presumable being the position where the cracks initiate.
