Effect of shot peening intensity on surface integrity of 18CrNiMo7-6 steel
Surface and Coatings Technology, 2021Abstract The surface integrity of components treated by shot peening is determined by many influencing factors, which are generally divided into shot peening process parameter, procedure parameter and machine parameter. To understand the influencing relationship of these parameters, and thereby obtain the appropriate peening intensity for the ...

Characterization of Nonmetallic Inclusions in 18CrNiMo7-6
Metallurgical and Materials Transactions B, 2018The 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, 2015In 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 ...

Fatigue fracture of surface-modified layers in 18CrNiMo7-6 carburized steel
Engineering Failure Analysis, 2022Abstract 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.

Investigation of Fatigue and Flaw Tolerance Performance of 18CrNiMo7-6 Case-hardening Steel
Proceedings of the Vertical Flight Society 76th Annual Forum, 2020The aim of this study is to evaluate the effect of small defects on the fatigue life of the 18CrNiMo7-6 material. The evaluations are based on comparisons of S/N curves, which are obtained through coupon-level fatigue testing of pristine and intentionally flawed specimen sets.
