| Abstract Scope |
Additive Manufacturing allows for the rapid and on-demand production of samples for materials development, but this throughput is often significantly limited by bottlenecks in characterization. While there has been significant research into high-throughput mechanical characterization, many functional properties still require tedious methods not optimized for AM. In this work, novel methodologies for characterizing functional properties are developed, alongside corresponding miniaturized AM samples: optical dilatometry is adapted to rapidly measure the anisotropic thermal expansivity of AM samples; soft magnetic properties are estimated from the reaction of AM samples in graded magnetic fields. These techniques are then used to explore a large feature space of Fe-Ni alloys printed by Directed-Energy Deposition, and their accuracy and throughput evaluated. It is shown how these techniques enable a Sequential Learning framework, where they can be used for screening and exploration and paired with lower throughput but more accurate methods. |
