Abstract

This work is devoted to the topic” Investigation of the microstructure and hardness of 20GL steel samples cut from a wedge-shaped and a side frame after volume-surface quenching ”. Recently, the railways of Asia and the Russian Federation are more than two dozen fractures of the side frames of trucks of freight cars every year. Each case is a potential source of an accident or crash. In addition, when carrying out scheduled repairs of freight cars, about a thousand side frames and truck bolsters are rejected.
