The Synchrotron Radiation for Steel Research
Advances in Materials Science and Engineering, Volume 2016, Issue 1, 2016., 2016 The synchrotron X‐ray radiation is a great tool in materials characterization with several advantageous features. The high intensity allows clear interaction signals and high energy of X‐ray yields higher sampling volume. The samples do not need extra preparation and the microstructure is therefore not affected. With the tunability of the X‐ray energy,

Influence of Microalloying on the Surface Layer of a Carbonitrided Steel 18CrNiMo7-6
, 2021 To further enhance the performance of case hardening steels, the surface layer is thermochemically treated. By carbonitriding, a thermochemical process by which carbon as well as nitrogen are brought into the surface layer, the tooth flank load capacity of case hardening steel gears can be dramatically improved in comparison to those elicited by ...

Calculation of sub-surface-initiated fatigue fractures in gears [PDF]
, 2019 Power-transmitting gears are typically heat-treated, most often case-hardened, to improve the fatigue strength and therefore to ensure higher fatigue life.

Growth of Subsurface Fatigue Fractures in Large‐Size Bevel Gears
Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 2, Page 640-652, February 2026.ABSTRACT Large‐size bevel gears are commonly used in marine industry for the applications of propulsion, such as azimuth thrusters. The gears are typically designed for specific use, as they are directly transferring power from one component to another.
