Fanciful FRET

Science's STKE, 2006
The validity of experiments based on Förster resonance energy transfer (FRET), an imaging technique widely used to measure protein-protein interactions in living cells, critically depends on the accurate and precise measurement of FRET efficiency. The use of FRET standards to determine FRET efficiency, and a consideration of such factors as how the ...

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 wear and fatigue in press-fitted railway axle: A simulation study of the influence of stress relief groove

International Journal of Fatigue, 2019
In this paper, a finite element model for the prediction of fretting fatigue crack initiation in the full-scale railway axle was proposed, which took into account the influence of the stress redistribution due to fretting wear on the fretting fatigue ...

Effect of micro-arc oxidation on fretting wear behavior of zirconium alloy exposed to high temperature water

Wear, 2019
Flow-induced vibrations can result in fretting wear damage to the surfaces of clad fuel rods (tubes) against their supports in nuclear power plants. One possible solution to this problem is using oxide coatings.

Effects of secondary orientation and temperature on the fretting fatigue behaviors of Ni-based single crystal superalloys

Tribology International, 2019
A dovetail fixture for fretting fatigue test was designed. Fretting fatigue experiments were performed for Ni-based single crystal (NBSX) superalloys at 600 and 700 °C in two secondary orientations, [110] and [010]. The influence of secondary orientation

Fretting Initiated Crevice Corrosion of 316LVM Stainless Steel in Physiological Phosphate Buffered Saline: Potential and Cycles to Initiation.

Acta Biomaterialia, 2019
Mechanically assisted crevice corrosion (MACC) has been associated with implant failure in vivo and is a serious concern in numerous metallic implant systems. Stainless steel medical devices may be subjected to fretting and crevice corrosion in the human

Effect of normal force on the fretting wear behavior of Inconel 690 TT against 304 stainless steel in simulated secondary water of pressurized water reactor

Tribology International, 2018
For understanding the long term fretting mechanism, the effect of normal force on the fretting wear behavior of 690 TT heat transfer tube against 304 stainless steel (SS) ball in simulated secondary water with 106 total fretting cycles was studied.

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.
