| Abstract Scope |
Additive manufacturing (AM) is a rapidly growing field; however, the material has not been adequately characterized and compared to that of conventional wrought or cast materials.
Stainless steel 316L has a wide range of applications in the aerospace and biomedical fields. This work aimed to generate a dataset of different material characteristics for SS316L alloy produced using laser powder bed fusion (L-PBF) and laser directed energy deposition (L-DED) processes. Two powder blends from 316L were received from two different powder suppliers. The chemical composition has no significant effect on the as-built microstructure. The microstructure in the case of L-PBF is much finer than that in the case of L-DED. However, the microstructure after heat treatment revealed different microstructural characteristics. The obtained mechanical properties and stress-corrosion cracking resistance of the additively manufactured material are above those of the wrought alloy. |
