Study on the influence of various 316L atomized powders on the microstructures and mechanical properties of parts obtained by Laser Powder Bed Fusion process
Year: 2017
Type: conference-paper
Abstract: 316L stainless steel complex parts, manufactured by Laser Powder Bed Fusion (L-PBF), are now standard products for metal additive manufacturing (AM) workshops. In this study, conducted in the framework of H2020 SUPREME funded project, five batches of 316L powders, either gas- or wateratomized, and having different particle size distributions (10-45μm, <45μm and <53μm) were characterized and used to produce samples on a roller L-PBF machine. The effects of powder chemistry and particle size distribution (PSD) on others powder properties, minimal energy density for >99% dense parts and parts mechanical properties, as well as the effect of solution annealing on mechanical properties, were studied. The mechanical properties of the samples after AM and after heat treatment were compared to each other and to those of wrought and L-PBF 316L from literature.
