INFLUENCE OF PRODUCTION PRACTICE ON FRACTURE TOUGHNESS OF RAILS

Linear fracture mechanics were used to investigate fracture toughness anisotropy in R-65 type railway rails after rolling in a conventional two-roll finishing stand and a universal four-roll stand. The investigation showed the advantages of slow enclosed cooling in improving the cracking resistance of rail steel. Data were obtained on the change in crack-propagation resistance during service.
