Abstract Scope |
It is now well known that the AM build process creates segregated microstructures with significant differences from those of traditional wrought alloys. However, understanding the relationships between the build conditions and the concomitant microstructures is key to developing appropriate post-build heat treatments that will produce parts with reliable and predictable properties. This presentation examines the local microstructures from comprehensively characterized locations within a set of 3D builds and from individual laser traces. Detailed analyses from the sets of IN718 AM-Bench artifacts will be presented, including the solidification and post-processed microstructures, compositional heterogeneities, grain structures and orientations, and melt pool geometries. The data from the characterizations of the benchmark artifacts will be used to evaluate the fidelity of simulations submitted for the microstructure challenges. |
