项目摘要

Additive manufacturing is revolutionizing manufacturing by enabling layer-by-layer production of components from computer models. Metal additive manufacturing has been adopted by industry at a slower pace compared to 3D printing of plastics, polymers, and hydrogels. This Grant Opportunities for Academic Liaison with Industry (GOALI) project involves fundamental research to enable expansion of additive manufacturing of metals. The process enabled by this research will be focused on a specialized type of metals, called `nano-twinned' metals, which exhibit simultaneous high strength, high ductility, and high electrical conductivity. These properties are enabled by their special microstructure, which is distinctly different than conventional metals. Specifically, in the atomic structure of these metals, parallel arrays of specialized boundaries (twin boundaries, TBs) form in which atoms have a mirror symmetry with respect to the boundary. These boundaries strengthen the metal. Also, electric current can readily flow through mirror atoms in the boundary, making these materials well-suited for electrical applications. This fundamental research will result in an additive manufacturing process that can be adopted in many industries such as for structural applications, interconnects in electronics, and sensors. This research may result in a viable commercial low-cost 3D printer for metals, which can be adopted by academic research labs, educational facilities, and small manufacturing enterprises (SMEs). The partnership with industry on this GOALI project will facilitate such transition.In this project, fundamental research will be conducted on a new process for additive manufacturing of metals with controlled twin lamella thickness and twin density, and hence controlled mechanical and electrical properties. The process is based on a localized pulsed electrodeposition process. Nano-twinned metals are ultrafine-grained or fine-grained metals that contain a high density of layered nanoscale regions. These regions are divided by coherent twin boundaries. Nano-twinned metals have an unprecedented combination of ultrahigh strength, high ductility, and high electrical conductivity. This type of metal in bulk form can be synthesized via various approaches including electrodeposition, recrystallization, phase transformation, and sputter deposition, and plastic deformation processing. However, there is no current process for additive manufacturing of nano-twinned metals. This project will develop a theoretical understanding of additive manufacturing of nano-twinned metals by localized pulsed electrodeposition (L-PED) using combined multi-physics simulation and multi-scale experiments. In addition, nano-twinned metals will be manufactured by 3D L-PED and the process-structure-property relationship of the printed metals will be investigated.

增材制造正在通过从计算机模型中逐层生产组件来彻底改变制造。与塑料，聚合物和水凝胶的3D打印相比，行业采用了金属添加剂制造。这项与行业联络的赠款机会（Goali）项目涉及基础研究，以扩大金属的添加剂制造。这项研究启用的过程将集中在一种专用类型的金属上，称为“纳米 - 二威”金属，该金属同时具有高强度，高延展性和高电导率。这些属性由它们的特殊微观结构启用，这与常规金属截然不同。具体而言，在这些金属的原子结构中，专门边界（双边界，TBS）形式的平行阵列，其中原子与边界具有镜像对称性。这些边界增强了金属。同样，电流可以轻松地通过边界中的镜像原子流动，使这些材料适合电气应用。这项基本研究将导致在许多行业（例如结构应用，电子设备中的互连和传感器的互连）中采用的增材制造过程。这项研究可能会导致可行的商业低成本3D金属打印机，该打印机可以由学术研究实验室，教育设施和小型制造业企业（SME）采用。与行业在此目标项目上的合作关系将有助于此类过渡。在该项目中，将对具有受控双层薄层厚度和双重密度的金属增材制造的新过程进行基础研究，因此将进行机械和电气的控制。该过程基于局部脉冲电沉积过程。纳米二线金属是超铁粒或细粒金属，其中包含高密度的分层纳米级区域。这些区域除以连贯的双界边界。纳米二线金属具有超高强度，高延展性和高电导率的前所未有的组合。可以通过各种方法合成这种散装形式的金属，包括电沉积，重结晶，相变和溅射沉积以及塑性变形处理。但是，目前没有用于纳米二线金属增材制造的过程。该项目将通过局部脉冲电沉积（L-PED）使用组合的多物理模拟和多尺度实验来对纳米二winned金属的添加剂产生理论理解。此外，将通过3D L-PED制造纳米二温金属，并将研究印刷金属的过程结构 - 特制关系。
