“…To study the gigacycle fatigue strength beyond 10 8 cycles with reasonable testing times, new testing techniques based on ultrasonic loading frequencies of 20 or 30 kHz have been developed for the last 25 years . Nevertheless, the influence of the frequency on the fatigue strength of materials is a complex subject and remains controversial in the literature . Indeed, a high frequency can lead to self‐heating of the specimen that may induce instability of the microstructure and degradation or improvement of the mechanical properties of the material, which in turn, depend both on the loading type and on the operating environment.…”

It is well‐known that the high cycle fatigue (HCF) strength of steel components is influenced by a lot of factors depending on both material, loading (including environment), specimen or component geometry (design), and manufacturing process. Based on a literature review of a lot of experimental data, a synthesis is proposed in this paper to discuss the effect of the structural and operational factors on the very high cycle fatigue (VHCF) characteristics of steels. HCF and VHCF regimes are distinguished in terms of failure mechanisms and S‐N curve shapes for high and low strength steels. Then, the effect of the microstructural and mechanical features on the VHCF resistance is debated as different parameters (microstructure, inclusion size type and depth, hydrogen, environment, maximum tensile strength, and residual stresses). Next, the influence of the loading conditions is addressed by taking into account both the frequency effect, the highly stressed volume, the loading type, and loading ratio. Finally, the influence of the testing techniques used in VHCF experiments is discussed.

This work presents a new ultrasonic fatigue testing device for studying the initiation and propagation mechanisms of internal microstructurally short fatigue cracks using in situ synchrotron tomography. Its principle is described as well as the method used for automatically detecting crack initiation and its subsequent growth. To promote internal crack initiation, specimens containing internal casting defects were tested between the high cycle and very high cycle fatigue regimes (10 7 -10 9 cycles). Preliminary results show the ability of this new device to initiate an internal microstructurally short crack in a reasonable testing time and monitor its growth.

“…(2) would work well if inputting higher HV values in case of the material is hardened under extremely high strain-rates (Guennec et al, 2014;Lee and Liu, 2006). Therefore, evaluation of the size effect on fatigue strength needs details of hardness and associated tensile strength under ultrasonic frequency.…”
