INVESTIGATION OF THE EFFECT OF THE STRENGTH OF RAILROAD RAILS ON THE FORMATION OF CONTACT-FAGIGUE DEFECTS DURING USE

ISSLEDOVANIE VLIYANIYA PROCHNOSTI ZHELEZNOROZHDENYKH REL'SOV NA OBRAZOVANIE KONTAKTNO-USTALOSTNYKH POVREZHDENII V EKSPLUATATSII

It is shown that one of the main causes of the formation of contact-fatigue defects in rails is strong cold-working of the peripheral metal layers and development of considerable stresses at the boundaries between the cold-worked and non-cold-worked layers. It is found that an increase of the static strength of steel by any means (heat treatment, alloying or modification of steel) sharply reduces its cold-workability and thereby cuts down its tendency to the formation and development of contact-fatigue damage.
