The effect of quenching and defects size on the HCF behaviour of Boron steel [PDF]
, 2014 This work investigates the effect of natural and artificial surface defects and quenching on the fatigue strength of a Boron steel (22MnB5). A vast experimental campaign has been undertaken to study the high cycle fatigue behaviour and more specifically ...

Microscopic Damage Evolution During Very High Cycle Fatigue (VHCF) of Tempered Martensitic Steel
Procedia Engineering, 2016 AbstractDimensioning of high-strength steels relies on the knowledge of Wöhler-type S/N data and the assumption of a fatigue limit for applications where the number of load cycles exceeds 107. Very high cycle fatigue (VHCF) experiments applied to a 0.5C-1.25Cr-Mo tempered steel (German designation: 50CrMo4) revealed surface crack initiation at prior ...

Very High Cycle Fatigue for single phase ductile materials: slip band appearance criterion [PDF]
, 2013 The DISFAT project is a French project financially supported by the French National Agency for Research (ANR). It aims at a deeper understanding of mechanisms leading to crack initiation in metals and alloys under Very High Cycle Fatigue loading (VHCF ...

Crack growth behaviour of aluminium wrought alloys in the Very High Cycle Fatigue regime [PDF]
MATEC Web of Conferences, 2018 Investigations have shown that in the regime of Very High Cycle Fatigue (VHCF) “natural” crack initiation often takes place underneath the material surface leading to crack propagation without contact to atmospheric components.

Ultrasonic VHCF Tests on Very Large Specimens with Risk-Volume Up to 5000 mm3
Applied Sciences, 2020 The research on the size-effects in Very-High-Cycle Fatigue (VHCF) has recently drawn the attention of several scholars. The fatigue cracks in VHCF originate from the largest defect present within the loaded material volume (risk-volume) and the larger ...

Simulation of microstructural damage evolution during very high cycle fatigue (VHCF) using the boundary element method [PDF]
PAMM, 2013 AbstractA simulation model for damage evolution in slip bands under VHCF condition is presented. By use of a numerical method it is applied to a real simulated microstructure of AISI304. It considers orientations of slip systems as well as individual anisotropic elastic properties in each grain.

Procedia Structural Integrity, 2016 AbstractThe study is an overview of recent investigations dealing with the fatigue damage in the HCF and VHCF regime of 0.5C-1Cr martensitic steel (German designation: 1.7228) in a tempered condition. The experimental part is focussed on the microstructural characterization regarding crystallographic orientation, reconstruction and grain size ...
