Abstract Scope |
Functional magnetic materials exhibiting magnetic-shape-memory or magnetocaloric effects have recently been fabricated by binder jet 3D printing, direct laser deposition, selective laser melting, and 3D ink printing additive manufacturing (AM). These AM techniques are fundamentally different for part shaping and steps for during-build or post-build processing. Consequently, each technique results in functional magnetic materials with differing final microstructures and functional magnetic properties. Energy-beam-based methods (melting of feedstock powder) build dense parts, but also generate complex and inhomogeneous microstructures due to rapid solidification and repeated heating cycles. Non-energy-beam-based methods (e.g. binder connects powder particles) build highly porous green samples, but avoid microsegregation and allow microstructural control via post-processing.
In this talk, binder jetting and direct laser deposition, structural characterization (2D/3D), and property evaluation will be presented for Ni-Mn-based functional magnetic materials. These materials were assessed in both as-printed and heat-treated states. Results will be compared to samples fabricated by other methods. |
