Texture control of 316L parts by modulation of the melt pool morphology in selective laser melting Article dans une revue avec comité de lecture; ; ; ; ; ;
KOUTIRI, Imade; PESSARD, Etienne; SAINTIER, Nicolas (Elsevier, 2019)
In this study, 316L parts were fabricated with the selective laser melting additive layer manufacturing process using unidirectional laser scan to control their texture. The melt pool shape, microstructure and texture of ... -

Article dans une revue avec comité de lecture; ; ;DAL, Morgan; SCHNEIDER, Matthieu (Laser Institute of America, 2019)
The increase of process simulations in industry leads to the need of accurate knowledge of material thermal properties. As the determination of liquid metal properties is quite difficult, this article presents an experimental ...

Article dans une revue avec comité de lecture(Cambridge University Press (CUP), 2018)The wettability of the 304L steel is an important parameter in Liquid Metal Embrittlement studies. Empirically, it is found to be greatly enhanced by pre-exposure to oxygenated liquid sodium. The corrosion interface formed ...
