Resumo
The structure and mechanical properties of fragments from freight bogie solebars made of 20GL steel are determined in the initial normalized state and after thermal hardening by volume–surface quenching. This quenching is shown to increase the strength of a solebar fragment with a wall thickness of at most 20 mm almost twofold as compared to the normalized state and to increase its bearing capacity by a factor of approximately 1.5.
