Abstract
Additive manufacturing (AM) is a relatively new process for directly building metallic components in a layer-by-layer manner. This can reduce fabrication costs in alloys that are difficult to subtractively machine, especially for low volume, complex components. Due to the rapid solidification nature of the process, elemental segregation is a concern as it can detrimentally affect the resulting mechanical properties. Thus, post-processing homogenization heat treatments are applied to ensure effectiveness of the alloying system and obtain isotropic properties. Standards to guide post-processing of AM materials are still under development; thus, more information is needed on how the variability among vendors affects the resulting mechanical properties. This study evaluates the effectiveness of a homogenization heat treatment on the mechanical properties and microstructure of Blown Powder Deposition (BPD) Inconel 625 produced by four different vendors.
