There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
Recent advances in additive manufacturing (AM) reveal exciting opportunities to build materials with novel internal structures combined with intricate part geometries that cannot be achieved by traditional manufacturing approaches. The large space of potential material chemistries combined with non-equilibrium microstructures produced by enormous number of possible parameter combinations in AM presents a significant challenge for a systematic exploration and optimization of the final properties exhibited by AM parts. High throughput assays that are customized for AM, especially for its flexibility in spatial control, need to be developed to quickly and reliably determine structure property linkages for a variety of AM processes. The work proposed a set of protocols on various titanium alloys that can be used to screen a large library of material chemistries and different process histories in small sample volumes to establish associated structures property linkages in a high throughput manner.
