A mathematical model for the cylindrical grinding responses of 18CrNiMo7-6 alloy steel

, 2023
Abstract Due to its exceptional mechanical properties, 18CrNiMo7-6 alloy steel is one of the preferred materials for producing critical components of high-speed heavy-duty gearboxes. To study the relationship between cylindrical grinding parameters, i.e., workpiece speed, wheel speed and grinding depth, and grinding responses (grinding force ...

Distribution of Inclusions in 18CrNiMo7-6 Steel Billet and Its Relationship with Inclusion Compositions

Journal of Physics: Conference Series, 2020
Abstract The 18CrNiMo7-6 steel billet was prepared by the process of EBT→LF→VD→die casting and forging. The position distribution, composition, type and cause of inclusions in the billet were statistically analysed by ASPEX and scanning electron microscopy. The results show that there are obvious distribution differences of inclusions in

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.

Fatigue strength evaluation of case‐hardened components combining heat‐treatment simulation and probabilistic approaches

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 3, Page 745-765, March 2024.
Abstract In order to raise the hardness and strength of the surface layer of mechanical components and induce favorable residual compressive stresses, case‐hardening procedures have become established in the heat treatment of steel. In this work, a calculation concept for the fatigue strength of components that have been case‐hardened through ...
