Abstract Scope |
Additive manufacturing (AM) is highly customizable and can be used for the economic production of complex structures. 3D printed metals often contain coarse columnar grains, which may result in directional properties that may be deleterious of advantageous. To achieve the strict specifications needed for some structural applications, control of the microscopic structure and the promotion of grain refinement are crucial. Recent experimental advances allow for the visualization of dynamic solidification events in metals at unprecedented length- and timescales. This work presents the in-situ/ex-situ characterization of microstructural evolution during AM, with the aim of advancing our current understanding of microstructure development under AM conditions, and provides insights into alloy design approaches for AM. |
