Multi-modal strain mapping of steel crack tips with micrometre spatial resolution. [PDF]

J Synchrotron Radiat
Multi‐modal measurements combining X‐ray diffraction, X‐ray fluorescence and optical microscopy allow dynamic crystal recovery effects around martensitic steel crack tips to be studied. The measured strain field around the crack tip shows a significant departure from the predictions of linear elastic fracture mechanics.Due to their superior fatigue ...

Fatigue Strength Enhancement of Butt Welds by Means of Shot Peening and Clean Blasting

Metals, 2019
Shot peening is a mechanical surface treatment to improve the fatigue strength of metallic components. Similarities exist between regular shot peening and conventional industrial clean blasting. However, the main difference between these two processes is

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).

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.

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

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%.
