Effect of Water Jet Cavitation Peening on Short-Period Oxidation Behavior of Alloy 600 in PWR Primary Water

open access: yesMetals, 2023
Water jet cavitation peening (WJCP) was used to strengthen the surface of nickel-based alloy 600. Residual stress, hardness, surface roughness, microstructure, and short-period oxidation behavior in untreated (UT) and WJCP-treated alloy 600 were ...

Bending fatigue behavior of metastable and stable austenitic stainless steels with different surface morphologies

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 12, Page 4755-4770, December 2024.
Abstract The surface morphology has a significant influence on the fatigue behavior of components. For austenitic stainless steels (ASSs), this issue is even more pronounced due to their metastability. Based on the complex deformation mechanisms of metastable ASSs, which include dislocation slip, deformation twinning, and deformation‐induced ...

Fatigue Limit Estimation for Post‐Peened Induction‐Hardened and Tempered Steel Considering Changes in Surface Properties

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 12, Page 4607-4617, December 2024.
ABSTRACT Shot peening (SP) and fine particle peening (FPP) were performed as post‐treatments on induction‐hardened and tempered AISI 4140 steels. Furthermore, the combined effects of surface characteristics including changes in surface morphology, compressive residual stress, and hardness on the fatigue limit were quantitatively examined.

Enhancing the aggressive intensity of a cavitating jet by introducing a cavitator and a guide pipe

open access: yesJournal of Fluid Science and Technology, 2014
In order to enhance the aggressive intensity of a cavitating jet for practical applications, such as cavitation peening, a nozzle equipped with an additional nozzle upstream from the main nozzle, i.e., a cavitator, and a guide pipe downstream from the ...

Effect of multifunction cavitation treatment on the surface of thin plates of Al alloys

open access: yesResults in Materials, 2022
The high strength of a thin plate surface produced by peening treatment is not yet used in industrial products, even when the mechanical properties are improved, due to warpage after the surface treatment.

Estimating the fatigue limits for quenched and tempered steel rods treated with multifunction cavitation considering residual stress, hardness, and surface pits

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 11, Page 4000-4011, November 2024.
Abstract In this study, multifunction cavitation (MFC) was performed on low‐alloy steel (AISI 4140 steel) rods with different hardnesses to increase their fatigue limit. It was found that a high compressive residual stress was generated on the surface of steel rods by MFC and that the magnitude of the compressive residual stress tended to increase with
