Scaling invariance of fatigue crack growth in gigacycle loading regime [PDF]
Technical Physics Letters, 2010 The role of the collective behavior of defect ensembles at the crack tip and the laws of fatigue crack propagation in R4 high-strength steel have been studied under conditions of symmetric tension-compression gigacycle loading at 20 kHz. At every stage of the fatigue crack growth, replicas from the sample side surface were taken and studied by the ...

Gigacycle fatigue initiation mechanism in Armco iron [PDF]
International Journal of Fatigue, 2012 Abstract Microstructure irreversibility plays a major role in the gigacycle fatigue crack initiation. Surface Persistent Slip Bands (PSB) formation on Copper and its alloy was well studied by Mughrabi et al. as typical fatigue crack nucleation in the very high cycle fatigue regime.

Gigacycle fatigue data sheets for advanced engineering materials [PDF]
Science and Technology of Advanced Materials, 2007 Gigacycle fatigue data sheets have been published since 1997 by the National Institute for Materials Science. They cover several areas such as high-cycle-number fatigue for high-strength steels and titanium alloys, the fatigue of welded joints, and high-temperature fatigue for advanced ferritic heat-resistant steels.
