| Abstract Scope |
In situ mechanical testing using SEM has provided powerful characterization methods for a full understanding of the mechanical behavior of metals at small-scale. Micro-pillar compression is one of the most frequently used novel methods to extract the deformation mechanisms. To date, the most common technique for fabrication of micro-pillars is focused ion beam (FIB) milling of the bulk materials (or films), which requires several tens of hours of the equipment time, and the associated expenses. In this presentation, we report on an additive manufacturing (AM) process, termed localized pulsed electrodeposition (L-PED), that enables the fabrication of micro-pillars in a single step at low-cost in the room environment. This process allows direct deposition of micro-pillars in a few minutes to tens of minutes with great control over the microstructure. The micro-scale AM process may be a major step forward in enabling high-throughput investigation of the process-microstructure-property relationship of metals at small-scale. |
