THE FATIGUE STRENGTH OF RAILS WITH ELECTROLYTIC CORROSION DAMAGE

USTALOSTNAYA PROCHNOST' REL'SOV S ELEKTROKORROZIONNYMI POVREZHDENIYAMI

The effects of corrosion by electrolysis on the base of the rail are dealt with. Studies have revealed that electrocorrosion damage to the rail base rim decreases its fatigue strength, and thus leads to a decreased rail life by lowering the limit of endurance of the rail. Volume tempered rails with the same depth of corrosion as nonheat-treated rails are less affected so far as service life. With an increase in corrosion-damage depth of the base to 5 mm, the limit of endurance decreases from 31 to 24 kg/sq mm. Typical examples of transverse fractures initiated by corrosion and finalized by cyclical bending are shown.
