Abstract Scope |
Nanostructured materials provide advanced structural and functional properties by harnessing the unique interactions and properties found at the sub-micron scale. Nanoscale additive manufacturing promises new pathways for unlocking the benefits of nanomaterials through spatial control of microstructures. With this intersection of structural (extrinsic) and materials (intrinsic) size effects, new opportunities are afforded in designing nanomaterials that push away from traditional property tradeoffs like increasing strength decreases ductility. Leveraging the multimaterial printing capabilities of electrohydrodynamic redox printing (EHD-RP), we probe the interplay between feature size and prescribed nanostructuring such as localized porosity, microstructural gradients, and phase interfaces through size-effect studies on Cu, Zn, and Ni based materials. Using both in-situ and ex-situ nanomechanical tests, we investigate the competition and cooperation of these effects on ductility and failure at the nanoscale. By untangling the relationship between interacting microstructural mechanisms, these studies help provide the foundation for designing robust, failure-resistant nanoarchitected materials. |
