| Abstract Scope |
In nanostructured materials, interfaces are a dominating feature that drives mechanical performance. Nanoscale additive manufacturing has opened new methods for designing these interfacially dominated materials. In particular, electrohydrodynamic redox printing (EHD-RP) has demonstrated strong architecting capabilities through spatial control of grain size, multi-phase material printing, and production of far-from-equilibrium alloys. However, this technique relies on large electric fields that control the flight of metal-ion containing droplets and kinetically driven redox reactions to deposit metals and other materials from those droplets. To better understand the influence of these unique growth and formation conditions on the mechanical behavior of EHD-RP nanostructured materials, we use TEM and atom probe tomography (APT) to investigate both the structure and local chemistry of grain and phase boundaries in Ag, Cu, and Zn systems. Together with nanomechanical tests, we show how interfaces produced during the EHD-RP process impact structural properties like strength and deformability. |
