Abstract Scope |
This study investigated the relationship between microstructure and mechanical properties of hybrid additively manufactured (AM) stainless steel 316L. Here, two 316L parts were made using three separate processing techniques. In the first part, a laser powder direct energy deposition (LP-DED) perform was built on top of the same geometry mad via laser powder bed fusion (LPBF). For the second part, a LP-DED 316L preform was built on top of wrought material. Both parts were electric discharge machined into coupons for mechanical testing. Tensile testing was used to determine both bulk mechanical properties with respect to build orientation, as well as across the hybrid AM interface. Microhardness testing was also used to probe local mechanical properties across the interface. The microstructures of all samples were investigated using scanning electron microscopy including EDS and EBSD. This study represents the first known attempt at executing hybrid AM of 316L with a Meltio M450. |
