Fretting fatigue of steels with different strength
Original language description
The present work deals with the investigation of fretting influence on fatigue properties of steel parts with different strength. Two steels for railway sets - axles, EA1N carbon steel and EA4T heat-treated CrMo low - alloy steel with strength values 578, 676, 736 and 1050 MPa were investigated. t was found that in case of fatigue tests without fretting, higher fatigue limit corresponded to higher strength whilst specimens subjected to fretting fatigue showed fatigue limit not too different from each other. Microstructural changes in thin surface layer eliminated substantially the original differences in strength and could explain the suppression of the strength influence on the fatigue limit under the condition of fretting.
