| Abstract Scope |
Additive manufacturing (AM) requires new alloys to take advantage of this new processing space – localized heating, small volume melting, rapid solidification, repeat melting, etc. Currently used alloys were developed for cast, wrought or powder metallurgy applications and frequently show defects when processed by AM, for example build cracking of high γ’ Ni-based superalloys. To expedite alloy design and selection, a new approach has been developed that incorporates property targets with thermodynamic and electronic structure modeling with a rapid solidification analysis set of tools, including microstructure and properties, followed by powder production and AM build validation. The results of the approach across three different alloy families – high strength Al alloys, Ni-based superalloys and multi-principle element alloys – will be described with the implications for shortening turnaround time for exploring new compositions from years to just months and accelerating the adoption of AM.
