| Abstract Scope |
Critical to the future advancement of additive manufacturing (AM) technologies is the exploration of fundamental laser-material interaction paired with informed alloy powder development. The large-scale and "black-box" nature of commercial 3D printers limits the ability to pursue such studies due to powder and process control limitations. In this work, we will present our efforts to literally, out-of-the-box, probe fundamental AM process-microstructure-property correlations. The primary tool to pursue this consists of a suite of lasers in pump-probe configurations that interact with small (5g-10g) of layered powder materials in a controlled atmosphere, heated environment. The resulting densified materials can be interrogated for density, hardness, phase structures (XRD) and microstructural evolution, and other physical properties with a minimal volume of material. Further, novel alloy compositions can be rapidly and easily explored. Preliminary examples of this approach will be presented for conventional AM alloy compositions along with novel nanocrystalline alloy printed materials. |
