Fretting Fatigue Behaviour of Alloy Steel in the Very High Cycle Region [PDF]

MATEC Web of Conferences, 2019
It is well known that fretting fatigue strength is much lower than the fatigue strength of smooth specimens and the fatigue limit disappears. Many studies on fretting fatigue have been reported but most of the studies have not cover fatigue properties in

Corrosion in Modular Revision Hip Stem Tapers - A Retrieval Analysis. [PDF]

J Orthop Res
ABSTRACT In revision hip arthroplasty, modular stems enable intraoperative adjustment of the biomechanics of the hip to ensure a stable joint function even in complex anatomical cases. Modular stem junctions, however, carry the risk of junction degradation due to corrosive processes or even junction breakage.

Achieving ultrahigh fretting fatigue endurance in TB8 titanium alloy with hierarchical structure via triggering nanocomposite and phase transformation

Materials & Design, 2023
Extraordinary fretting fatigue endurance is critical for engineering structures prone to contact with expected long service lifetimes. Here, we propose a strategy to achieve ultrahigh fretting fatigue endurance in titanium alloy.

Microstructural evolution and oxidation in α/β titanium alloy under fretting fatigue loading

Friction, 2023
Coupling effects of fretting wear and cyclic stress could result in significant fatigue strength degradation, thus potentially causing unanticipated catastrophic fractures. The underlying mechanism of microstructural evolutions caused by fretting wear is
