Size Effect on the Fatigue Performance of 18CrNiMo7‐6 Alloy Steel
steel research international, 2021The 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.

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 ...

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.

Study of Structural Inheritance of Austenite in Nb‐Microalloyed 18CrNiMo7–6 Steel
steel research international, 2018Structural inheritance (SI) is a phenomenon in which the newly formed austenite retains the prior austenite grain size, shape, and orientation of the previous martensitic, bainitic, or even tempered martensitic microstructure. The present work studies SI in 18CrNiMo7–6 steel with 0.08 wt% Nb and compares it with that in a similar but non‐microalloyed ...

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.
