Conclusions

  1. 1.

    Alloying of rail steel containing 0.75% C with manganese or chromium has a positive effect on its susceptibility to thermomechanical damage at low temperatures. Microadditions of titanium have no effect on susceptibility to thermomechanical damage.

  2. 2.

    Raising the carbon content of high-strength rail steel reduces the work of fracture of samples with thermomechanical damage in impact bending tests, although this is partially due to a change in the overall toughness of the steel. It was found that raising the carbon content from 0.65–0.70 to 0.75–0.85% which is necessary to increase the contact-fatigue strength of the steel, does not substantially lower the resistance to thermomechanical damage.
