| Abstract Scope |
The rapid heating and cooling cycles over extended periods of time during additive manufacturing (AM) create metallurgical opportunities to generate novel solid-state phase transformation phenomena. This presentation showcases (I) selected recent results from the AUSMURI research team, and (II) provides a detailed expose of our efforts to combine AM process design and alloys design to achieve a new class of AM-enabled titanium-oxygen-iron alloys via laser directed energy deposition [1]. The role of advanced microscopy across multiple-length scales in informing the process design and alloy design approach will be discussed.
