Effect of shot peening coverage on residual stress and surface roughness of 18CrNiMo7-6 steel

International Journal of Mechanical Sciences, 2020
Abstract Shot peening is becoming a widely used surface strengthening technique for various key mechanical components for its enhanced influence on the fatigue performance. This technique allows to strengthen the mechanical properties of material via introduce a certain depth of compressive stress layer and change the surface topography. The relation

Fatigue fracture of surface-modified layers in 18CrNiMo7-6 carburized steel

Engineering Failure Analysis, 2022
Abstract A modified layer of a certain thickness is produced on the surface of 18CrNiMo7-6 alloy steel after carburizing and quenching that greatly affects the microstructure and fatigue properties of the material. In this work, the fatigue performance of each layer was studied.

Size Effect on the Fatigue Performance of 18CrNiMo7‐6 Alloy Steel

steel research international, 2021
The size effect on the fatigue performance of 18CrNiMo7‐6 alloy steel is investigated. From rotating bending fatigue tests at room temperature, the relationship between the stress amplitude and the number of cycles of specimens with different diameters is obtained.

Characterization of Nonmetallic Inclusions in 18CrNiMo7-6

Metallurgical and Materials Transactions B, 2018
The detrimental effect of nonmetallic inclusions (NMIs) in steels on, e.g., fatigue lifetime is well known. In order to increase the durability and safety of materials and components, inclusion control and a deep understanding of inclusion formation are essential.

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

steel research international, 2015
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 as a main alloying element in order to trigger the precipitation of nano‐sized Cu precipitates ...
