| Abstract Scope |
Additive manufacturing (AM) processes typically produce large temperature gradients, high solidification rates, and repeated cycles of heating and cooling. The local processing conditions experienced during AM (e.g., thermal gradients and solid-liquid interface velocities during solidification) will dictate microscopic structure (i.e., microstructure) evolution. Here we visualize melt pool dynamics and solidification of metallic alloys during simulated AM by real-time imaging (e.g., synchrotron x-ray and dynamic transmission electron microscopy) and computational modeling to link local processing conditions to microstructure development. A deeper understanding of solidification under AM conditions is needed to optimize processing conditions across AM technologies, predict and control microstructure evolution and resulting properties and performance, and design alloys for AM. |
