EFFECTS OF SHOT PEENING ON HARDNESS OF 18CRNIMO7-6 STEEL BASED ON FINITE ELEMENT ANALYSIS

Jixie qiangdu, 2022
So far, most of the numerical studies on shot peening are limited in the effects of shot peening parameters on the residual stress and surface morphology. There is still lack of numerical research on shot peening parameters on the hardness.

Application of gradient severe shot peening as a novel mechanical surface treatment on fatigue behavior of additively manufactured AlSi10Mg [PDF]

, 2023
Post-processing methods can be crucial in addressing the associated anomalies of the as-built state of additively manufactured materials. In this study, for the first time, the effects of gradient severe shot peening as a novel mechanical surface ...

Influence of cryogenic grinding surface on fatigue performance of carburised 27MnCr5 [PDF]

, 2023
Automotive transmission components are subjected to cyclic loads and, thus, must have a reliable fatigue performance. Since fatigue cracks nucleate at the surface, it is necessary to guarantee that its surface integrity accomplishes the required ...

Impact of various heat treatments on the microstructure evolution and mechanical properties of hot forged 18CrNiMo7-6 steel [PDF]

, 2017
Carburizing is a method of enhancing the surface properties of components, primarily made from low to medium carbon steels, such as shafts, gears, bearings, etc. Carburized parts are generally quenched and tempered before being put into service; however,

Growth of Subsurface Fatigue Fractures in Large‐Size Bevel Gears

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 2, Page 640-652, February 2026.
ABSTRACT Large‐size bevel gears are commonly used in marine industry for the applications of propulsion, such as azimuth thrusters. The gears are typically designed for specific use, as they are directly transferring power from one component to another.

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 ...

HEAT AFFECTED ZONE MICROSTRUCTURE OF WELD JOINT PREPARATION IN ARTIFICIAL MANNER [PDF]

, 2019
This paper presents two possibilities of martensitic (fine grain and coarse grain) microstructure preparation. These microstructures are present as sub-zones in the heat-affected zone of welded joints, but due to the narrow region of HAZ in a real weld ...
