Аннотация
The fracture toughness of freight bogie solebars made of low-carbon 20GFL steel is studied in the normalized state and after volume–surface quenching (VSQ). The fracture strength is estimated using acoustic emission and the critical J integral. VSQ is shown to increase Jc of the solebar material by a factor of ≈1.5, and its static strength is higher than that after normalization by ≈1.7 times.
