Plain fatigue and fretting fatigue behaviors of 17-4PH steel subjected to ultrasonic surface rolling process: A comparative study

Surface & Coatings Technology, 2020
The effect of ultrasonic surface rolling process (USRP) on surface integrity, plain fatigue (PF) and fretting fatigue (FF) behaviors of 17-4PH steel was contrastively studied, and their internal mechanisms were discussed.

Fretting fatigue under variable loading below fretting fatigue limit

Fatigue & Fracture of Engineering Materials & Structures, 2006
ABSTRACTThe fatigue limit diagram provides the critical condition of non‐failure against fatigue under constant amplitude loading. The fatigue limit diagram is usually considered to give the allowable stress if every stress component is kept within the fatigue limit diagram. In the case of variable amplitude fretting fatigue, however, this study showed

Fretting Corrosion and Fretting Fatigue

1982
Two metals and alloys, in intimate contact, but with a small amount of relative motion between them, will often show excessive weight losses. If the relative motion between the parts is caused by applied stresses the parts may also suffer from premature fatigue failures.

An investigation of fretting fatigue behavior and mechanism in 17-4PH stainless steel with gradient structure produced by an ultrasonic surface rolling process

, 2020
A gradient structure layer was fabricated on 17-4PH specimens using an ultrasonic surface rolling process. The separation-factor methods confirmed that residual compressive stress played a critical role in improving fretting fatigue (FF) life, while ...

Crystal orientation effect on fretting fatigue induced geometrically necessary dislocation distribution in Ni-based single-crystal superalloys

Acta Materialia, 2019
The effect of crystal orientation on fretting fatigue induced crack initiation and dislocation distribution is studied by in-situ SEM observation and electron back-scattered diffraction (EBSD) in this paper.

Fretting fatigue failure behavior of Nickel-based single crystal superalloy dovetail specimen in contact with powder metallurgy pads at high temperature

, 2020
Fretting fatigue failure behavior of DD6 Nickel-based single crystal superalloys dovetail attachment at 600 °C has been investigated. The contact surface material is oxidized at high temperature and the oxides are compacted on the contact surface.
