The effect of laser shock peening on hardness and microstructure in a welded marine steel

open access: yesThe Journal of Engineering, 2015
Residual stress is generally considered as the main criterion in laser shock peening for enhancement of fatigue life. However, changes in material hardness, microstructure and surface roughness can also affect component performance.

Laser Shock Peening for Fatigue Resistance [PDF]

open access: yesMaterials: Book of Abstracts, 2000
Abstract Laser shock peening is developing into a commercial surface enhancement process for increasing the fatigue life of metal components. The process produces deep residual compressive stresses into treated surfaces which inhibit the initiation and propagation of fatigue cracks.

Two‐step simulation approach for laser shock peening [PDF]

open access: yesPAMM, 2019
AbstractLaser shock peening (LSP) is a surface modification technique to introduce compressive residual stresses (RS) with a high magnitude in the near surface region of the material. Due to non‐linear interactions (e.g. laser absorption by plasma, shock wave propagation, etc.) and a high number of parameters, it is difficult to study and optimize the ...

The Formation and Hardening Mechanisms of Multiscale Gradient Structures Tailoring by Explosive Hardening and Annealing in Commercially Pure Titanium

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Gradient structures (GS) introduced by plastic deformation have been shown to effectively enhance the surface properties of metallic materials. However, the GS fabricated by existing methods often suffers from limited hardening depth and limited control over the GS layer, which constrain their engineering applications.
