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 ...

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.

SURFACE TOPOGRAPHY IMPROVEMENT OF 18CRNIMO7-6 STEEL USING THE TAGUCHI TECHNIQUE
The ball burnishing process provides a fast, cost-effective, and straightforward method to enhance the physical-mechanical properties and surface integrity of industrially manufactured parts. In this study, ball burnishing was applied to improve the surface topography of 18CrNiMo7-6 steel, with milling used as a pre-burnishing treatment.Dzierwa, Andrzej +3 more

Effect of shot peening coverage on residual stress and surface roughness of 18CrNiMo7-6 steel
International Journal of Mechanical Sciences, 2020Abstract 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

Micro-structure and surface layer properties of 18CrNiMo7-6 steel after multistep shot peening
Materials & Design, 2013Abstract The effects of multistep shot peening on the structure and mechanical properties of 18CrNiMo7-6 steel have been investigated using X-ray diffraction line profile analysis. X-ray diffraction data reveals the phase transformation from austenite to martensitic phase after SP treatments.
