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 ...

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 ...

The Influence of the Chemical Composition of Steel on the Limitation of Austenite Grain Growth in the High-Temperature, Low-Pressure Carburizing Process

Crystals
High-temperature low-pressure carburizing significantly reduces the time required to produce carburized layers. However, its application promotes austenite grain growth and, consequently, the formation of coarse acicular martensite.

In Situ Investigation of Microstructure Evolution and Stress Generation During Low‐Pressure Carburizing and Quenching by Means of Synchrotron X‐Ray Diffraction

steel research international, Volume 97, Issue 7, Page 3642-3662, July 2026.
This study uses in situ synchrotron X‐ray diffraction at the German Electron Synchrotron to analyze low‐pressure carburizing (LPC) in steels. The findings reveal surface carbon saturation and carbide formation kinetics, and phase‐specific stress development during quenching. The results show carbide kinetics depend on steel grade and size, while stress

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 ...
