Texture control of 316L parts by modulation of the melt pool morphology in selective laser melting
Olivier Andreau,Imade Koutiri,Patrice Peyre,Jean-Daniel Penot,Nicolas Saintier,Etienne Pessard,Thibaut de Terris,Corinne Dupuy,Thierry Baudin +8 more
TL;DR: In this article, a selective laser melting additive layer manufacturing process using unidirectional laser scan to control the texture of 316L parts were fabricated with the selective laser-melting additive layer (SLAM) manufacturing process.

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.

Experimental analysis of spatter generation and melt-pool behavior during the powder bed laser beam melting process
V Gunenthiram,Patrice Peyre,Matthieu Schneider,Morgan Dal,Frédéric Coste,Imade Koutiri,Rémy Fabbro +6 more
TL;DR: In this paper, an experimental analysis of spatter formation was carried out on an instrumented SLM set-up allowing the quantification of spatiotemporal ejections and possible correlation with melt-pool behavior.

Optimization and comparison of porosity rate measurement methods of Selective Laser Melted metallic parts
Thibaut de Terris,Olivier Andreau,Patrice Peyre,Frédéric Adamski,Imade Koutiri,Cyril Gorny,Corinne Dupuy +6 more
TL;DR: In this paper, the authors compare different methods for measuring parts density and propose optimal procedures to improve the porosity of selective laser melted (SLM) parts, in order to assess the physical origin of the different types of porosities.

High cycle fatigue damage mechanisms in cast aluminium subject to complex loads
TL;DR: In this article, the authors investigated the high cycle fatigue behavior of cast hypo-eutectic Al-Si alloys and found that two distinct and coexisting fatigue damage mechanisms occur in this material, depending on the presence of different microstructural heterogeneities.
