The actual service life of wind turbine gearboxes is often well below the desired 20 years.
One of the prevalent failure modes in gearbox bearing raceways is white structure flaking …

This second part of the review on defects as root cause of fatigue failure comprises the
origin, the nature and the effects of non-metallic inclusions. Topics addressed are the …

This third part of the review on defects as root cause of fatigue failure addresses cavities
(pores, micro-shrinkages, unmelted regions), defective microstructures and microcracks as …

The study aims to investigate the influence of rare earth (RE) addition on the rolling contact
fatigue (RCF) behaviour of M50 bearing steel. Ball-on-rod RCF experiments were conducted …

Alternating shear stress is a critical factor in the accumulation of damage during rolling
contact fatigue, severely limiting the service life of bearings. However, the specific …

Abstract 718H Pre-hardened mold steels with different Rare Earth (RE) contents were
prepared to investigate the influence of RE on microstructure evolution and mechanical …

This study aims to investigate the influence of rare earth (RE) addition on the friction and
wear behavior of M50 bearing steel. The results show that RE addition has little effect on …

The crack propagation in bearing steel with a non-metallic inclusion is analyzed by Voronoi
finite element method. The load applied on the Voronoi finite element model is obtained by …

Water immersion ultrasonic testing technology is widely used in non-destructive testing of
large ring forgings, but near-surface defects are difficult to identify in near-surface blind …

This paper focuses on the crack nucleation and crack propagation induced by a cluster of
carbides. The morphology of the carbides is extracted from scanning electron microscope …
