| Abstract Scope |
Additive manufacturing (AM) enables various advantages such as complex geometry and short supply chain. We have recently designed an additive-manufactured high-entropy Al alloy with strength even higher than cast Al7075 at ambient and elevated temperatures. With gas-atomization being the major time-consuming and costly step for further enhancement of the mechanical properties of AMed products, we propose to mimic the rapid solidification during AM with arc-melted samples. Such fast and high throughput experiment aims to accelerate the research pace of AM. We ask the following three questions: (1) to what extent do the laser-scanned microstructures resemble the AMed ones? (2) Does laser scanning manage to realize the conceived strength? (3) What are the critical factors that govern the microstructure-property relationship during laser scanning? These questions will be explored in depth with the aid of multi-scale SEM, TEM, and STEM characterization. Broad revelations for AM Al alloy design will also be discussed. |
