| Abstract Scope |
Additive manufacturing (AM) allows us to print the complex features of metamaterials necessary to enable their remarkable structure-mechanical properties. By combining materials in composites, we add another level of design freedom to realize unique material behaviors. Here, we create low-weight hybrid 3D microscale metal-ceramic metamaterials, enhancing the strength of purely metallic structures while still preserving their ductility. Our approach of coupling template-assisted electrodeposition (TAE) and atomic layer deposition (ALD) is highly flexible in creating Ni-Al2O3 triply periodic minimal surfaces (TPMS) with a highly conformal coating of the strengthening ceramic layer. The superior mechanical performance is assessed by in situ micro-compression while transmission electron microscopy (TEM) and transmission Kikuchi diffraction (TKD) revealed a dense network of dislocations and local grain refinement induced by plastic deformation. We present an AM approach for complex nanostructured and porous 3D micro-architectures while using low temperatures and outline advantages to previously reported work in the field. |
