Abstract Scope |
NiTi-based shape memory alloys created through additive manufacturing (AM) techniques such as selective laser melting and direct energy deposition show complex functional behavior and often heterogeneous microstructures that are highly sensitive to the processing parameters. While such sensitivity may pose some challenges in the application of the material, it also creates opportunities for insights into the processing-microstructure-property relationships of AM techniques as well as creating materials with novel functionalities. As examples, we discuss the opportunities brought about by creating controlled location-dependent functional response in a single 3-D printed part, application of AM NiTi as a sensory material for exploring microstructure-related variability in metallic AM processes, and development of an accelerated process parameter optimization framework to fabricate defect free functional AM parts. |
