Einfluss der Mikrolegierung auf die Randschicht eines carbonitrierten Stahls 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 ...

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 ...

Tailoring the Hardening Behavior of 18CrNiMo7-6 via Cu Alloying

, 2016
In order to improve the rolling contact fatigue (RCF) behavior of gear steels, a concept to increase their damage tolerance is developed alternatively to the conventional approach of improving the degree of steel cleanliness. For that purpose, Cu is used

Intermittent gear rattle due to interactions between forcing and manufacturing errors

, 2008
The interaction between eccentricity and an external forcing fluctuation in gear rattle response is investigated experimentally. The experimental rig consists of a 1:1 ratio steel spur gear pair, the input gear being controlled in displacement and the ...

Alternative heat treatment methods to traditional case carburizing for gear steels

, 2022
Three different commercially available American gear steels were heat treated using different processes and their microstructures and hardness profiles examined. These steels and corresponding heat treatments were compared to 18CrNiMo7-6 case carburizing

Procedure for selecting appropriate steels for machine design [PDF]

, 2010
Selection of steels for industrial purposes usually means choosing a type of steel to make a part or a product. The steel that is chosen must meet all the designer requirements. A quantitative selection procedure has been used to analyze the large amount
