Special Issue Information

Dear Colleagues,

Subcritical cracking of materials under fatigue (cyclic) loading is a problem of major concern in engineering due to the possibility of structural integrity loss when fatigue cracks develop in materials. The particular case of steel represents a topic of special importance due to the magnitude of steel production in the world, that makes it the main structural material.

This Special Issue, “Fatigue Cracks in Steel”, is dedicated to the latest scientific achievements in the field of crack propagation in steel under cyclic loading. Both reviews and articles are welcome, together with technical notes. This issue welcomes contributions of any kind in the field of fatigue crack growth in steels. All approaches will be considered, including theoretical, numerical, and experimental techniques. Any phase of the phenomenon of cracking can be analyzed, i.e., from the initiation to the propagation stage, and any environment can be highlighted, including aggressive or corrosive media.

It is our pleasure to invite you to submit a manuscript for this Special Issue.

The new generation of bearing steel has good comprehensive properties, which can satisfy most of the requirements of bearing steel in a complex environment. In the presented work, fatigue properties of 15Cr14Co12Mo5Ni2 bearing steel have been investigated by means of rotating bending fatigue tests on smooth bar specimens after carburization and heat treatment. Optical microscope, scanning electron microscopy, electron backscatter diffraction, and Image-Pro Plus software were used to analyze the fracture, microstructure, and carbides. The results suggest that the fatigue strength at room temperature and 500 °C is 1027 MPa and 585 MPa, respectively. Scanning electron micrographic observations on the fracture surface of the fatigue specimens at 500 °C show that fatigue cracks usually initiate from voids in the carburized case and oxide layer on the surface of steel. The failure mode in the carburized case is a quasi-cleavage fracture, and with the increase of crack propagation depth, the failure mode gradually changes to fatigue and creep-fatigue interaction. With the increase of the distance from the surface, the size of the martensite block decreases and the fracture surface shows great fluctuation. Full article
