VHCF, Tribology Characteristics and UNSM Effects of Bainite and Martensite Spring Steels
Metals, 2022 It has been reported that the duplex bainite microstructure obtained by austempering (AT) shows higher strength, ductility and impact toughness than quench and tempered (QT) martensite structure in SAE9254 spring steel.

The Effect of Microstructure on the Very High Cycle Fatigue Behavior of Ti-6Al-4V Alloy
MetalsCrack initiation plays a major role in very high cycle fatigue (VHCF) life, and the initiation of cracks is related to slip behavior. There is a need for improvement in the understanding of the influence of Ti-6Al-4V microstructures on VHCF performance ...

Effect of Surface Mechanical Attrition Treatment on the very high cycle fatigue behavior of TC11
MATEC Web of Conferences, 2018 As an important engine component material, TC11 (Ti-6.5Al-3.5Mo-1.5Zr-0.3Si) titanium alloy is subjected to high frequency cyclic loading and its failure occurs beyond 109 cycles.

Self-similarity of damage-failure transition and the power laws of fatigue crack advance
Fracture and Structural IntegrityWe propose the interpretation of the Finite Fracture Mechanics based on the criticality of damage-failure transition due to specific metastability of free energy release.

steel research international, EarlyView.Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse.

Applied Stochastic Models in Business and Industry, Volume 42, Issue 2, March/April 2026.ABSTRACT Fatigue is the most common reliability failure mechanism and has been studied widely since the 19th century. Material specimens are used in laboratory experiments to obtain fatigue test data. An S‐N curve is used to depict the relationship between the stress (or strain) S$$ S $$ and the number of cycles to failure N$$ N $$. Statistical methods

Comparison between Fractal and Statistical Approaches to Model Size Effects in VHCF
Metals, 2022 Size effects concern the anomalous scaling of relevant mechanical properties of materials and structures over a sufficiently wide dimensional range. In the last few years, thanks to technological advances, such effects have been experimentally detected ...

Numerical analysis of vhcf cruciform test specimens with non-unitary biaxiality ratios [PDF]
International Journal of Computational Methods and Experimental Measurements, 2019 With the development of new materials, it is now known that there is no such thing as a fatigue endurance limit, i.e., materials do not have infinite life when the stress level is such that there is no fracture up to 10 million (1E7) cycles. The problem of testing materials above this number of cycles is that most testing equipment operates well below ...
