The fracture toughness of an experimental bainitic crossing steel (B.C.S.) (TM-MF-012)

The fracture toughness of an experimental bainitic steel, intended for use in points and crossing, has been measured. Specimens were taken from a wrought block and a rolled rail and these were tested at -15°C using various loading rates. It was found that the steel's fracture toughness was not sensitive...
