Journal ArticleDOI
Laser shock processing of aluminium alloys. Application to high cycle fatigue behaviour
TL;DR: In this article, the role of laser shock processing (LSP) on the cyclic properties of A356, Al12Si and 7075 aluminium alloys was evaluated, and major contributors to the fatigue performance improvements were investigated in order to determine the optimum shock conditions.
Journal ArticleDOI
Surface modifications induced in 316L steel by laser peening and shot-peening. Influence on pitting corrosion resistance
TL;DR: The influence of laser peening on the electrochemical behavior of 316L stainless steel in a saline environment was evaluated in this paper, where surface modifications were investigated as they might have beneficial effects on the corrosion behavior.
Journal ArticleDOI
Reduction of porosity content generated during Nd:YAG laser welding of A356 and AA5083 aluminium alloys
TL;DR: In this paper, the porosity content in laser beads was extensively studied, with the use of different experimental method (X-ray radiography+image analysis, tomography), in order to check the influence of mechanical surface preparation as well as process parameters (single or dual spot, different welding speeds).
Journal ArticleDOI
Influence of SLM process parameters on the surface finish, porosity rate and fatigue behavior of as-built Inconel 625 parts
TL;DR: In this paper, an Inconel 625-manufactured by SLM, using a hatching + contour procedure, was analyzed to understand fatigue crack initiation and an optimum set of parameters was found to deliver the best surface roughness combined with low porosity.
Journal ArticleDOI
