Stress Double Shot Peening to Improve Residual Stress Distribution. The Effect of Pre-tensile Stress and Peening Angle on Residual Stress Distribution.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 2000
The technique of shot peening is commonly used to increase fatigue limit. However, there are many difficulties in applying it to very high HV steel. To overcome these problems, the authors proposed stress double shot peening. This technique is applied to induction-heated steel (IH steel).

Anti‐Slip Material‐Based Strategies and Approaches

Advanced Materials Technologies, EarlyView.
This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.

In Situ Acoustic Monitoring of Focused Femtosecond Pulse Duration in Air

Laser &Photonics Reviews, EarlyView.
Air‐breakdown acoustics at the laser focus is used to determine femtosecond pulse duration with a simple USB microphone. By chirp‐tuning and compressing 1030 nm pulses from 241 to 50 fs, the acoustic amplitude scales inversely proportional to the square root of the pulse duration, enabling in situ readout over 50 fs–5 ps—crucial for precise pulse ...

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

steel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Finite element analysis of effect of double shot peening on residual stress of 18CrNiMo7-6 gear steel

Jixie chuandong, 2023
ObjectiveTo address the issues of uneven residual compressive stress distribution and high surface roughness in gears after shot peening, this study investigates the effect of double shot peening on the surface integrity of 18CrNiMo7-6 carburized gear steel.MethodsA shot peening model with random shot distribution was established using Abaqus software.

Fatigue response of as built DMLS processed Maraging Steel and effects of machining and heat and surface treatments [PDF]

, 2018
The main motivations for this study arise from the need for an assessment of the fatigue performance of DMLS produced Maraging Steel MS1, when it is used in the \u201cas fabricated\u201d state. The literature indicates a lack of knowledge from this point

Press Hardening for Sustainable Lightweight Chassis Design in Heavy‐Duty Vehicles: A Material Performance and Life Cycle Assessment Approach

steel research international, EarlyView.
The article explores how high‐strength steels and press hardening revolutionize lightweight chassis design for heavy‐duty vehicles. It reveals that press hardened steels combined with shot peening can cut weight by up to 34% and reduce environmental impact by 21%–32%.

Increase in Fatigue Limit of Gears by Compound Surface Refining using Vacuum Carburizing, Contour Induction Hardening and Double Shot Peening

Proceedings of the 1992 Annual Meeting of JSME/MMD, 2000
The surface refining method is a useful technique to improve the fatigue limit of gears. One of the methods is the Carburizing Method. To increase the fatigue limit of the Carburized gears, the following five techniques need to be developed:a)Reduce abnormal surface structure. b)Obtain a fine grain size. c) Decrease the retained Austenitic structure. d)
