| Abstract Scope |
Directed energy deposition (DED) additive manufacturing (AM) with multiple feedstocks can be used to join dissimilar materials or create gradients in compositions and therefore properties. However, when joining metal alloys in the molten state, the mixing of the dissimilar materials may result in cracking or fragile joints due to deleterious phase formation, solidification cracking, or microsegregation. Additionally, once a compositional pathway is designed that avoids these issues, the actual fabrication of components along that pathway is impacted by dilution between subsequent tracks or layers of material. This talk will describe experimentally validated computational tools that can be used when joining dissimilar materials via DED AM to avoid deleterious phase formation, microsegregation, and solidification crack susceptibility, while also considering dilution effects to fabricate designed components. |
