Steels for bearings
TL;DR: In this paper, the structure and properties of bearing steels prior to the point of service are first assessed and described in the context of steelmaking, manufacturing and engineering requirements, followed by a thorough critique of the damage mechanisms that operate during service and in accelerated tests.
Journal ArticleDOI
Course of SN-curves especially in the high-cycle fatigue regime with regard to component design and safety
TL;DR: In this paper, material and manufacturing dependent recommendations are given with regard to the course of the SN-curve in the very high-cycle area, where the authors show that a decrease of fatigue strength with increased number of cycles still occurs, even if corrosion or temperature effects are excluded.
Journal ArticleDOI
Very high cycle fatigue – Is there a fatigue limit?
TL;DR: In this paper, the authors give an overview of the present state of research on fatigue strength and failure mechanisms at very high number of cycles (N f ǫ>10 7 ). Testing facilities are listed.

Safe life and damage tolerance aspects of railway axles – A review
Uwe Zerbst,Stefano Beretta,G. Köhler,A. Lawton,Michael Vormwald,H.Th. Beier,Christian Klinger,I. Černý,John Rudlin,Thomas Heckel,Dietmar Klingbeil +10 more
TL;DR: In this article, the authors give an overview on safe life and damage tolerance methods applied to railway axles. And they describe failure scenarios due to fatigue crack initiation and propagation, specific features such as corrosion and impact damage from flying ballast are discussed.

Effect of microstructure on ultra-high cycle fatigue behavior of Ti-6Al-4V
Jun Zuo,Z.G. Wang,En-Hou Han +2 more
TL;DR: In this article, the fatigue behavior of Ti-6Al-4V alloy with the bimodal and basketweave microstructures has been investigated and the results show that the S-N curves of Ti 6Al 4V continuously decrease with increasing the number of cycles to failure and have no horizontal asymptote in the regime of 10(5) to 10(9) cycles.

There is no infinite fatigue life in metallic materials
TL;DR: In this paper, the shape of the S-N curve beyond 10 7 cycles is unknown except in some statistical approaches, and this is also true for the fatigue limit, and the standard deviation applied to the average fatigue limit is certainly not the best way to reduce the risk of rupture in fatigue.

Factors influencing the mechanism of superlong fatigue failure in steels
Y Murakam,T Nomoto,T Ueda +2 more
TL;DR: In this article, a particular fatigue fracture morphology in the vicinity of the fracture origin (non-metallic inclusions) of a heat-treated alloy steel, SCM435, was tested to N ≥ 10 8.

Stepwise S-N curve and fish-eye failure in gigacycle fatigue
Nishijima,Kanazawa +1 more
TL;DR: In this paper, a stepwise shape in the S-N curve is represented by a fish-eye facet on the fracture surface of a material, showing that materials with a hardened surface fail from the surface only at high stresses, and at low stresses from the inside.

Gigacycle fatigue of ferrous alloys
TL;DR: In this paper, the authors determined the very long fatigue life of ferrous alloys up to 1 x 10 10 cycles at an ultrasonic frequency of 20 kHz, and a good agreement was found with the results from conventional tests at a frequency of 25 Hz by Renault between 10 5 and 10 7 cycles for a spheroidal graphite cast iron.

TL;DR: In this article, a sum up of this work is given in this paper, with many results and a discussion of mechanisms, as well as the results and mechanisms discussed in this work.
