Abstract
Electron microscopy enhances our understanding of metallic materials at small scales, which is central for developing sustainable materials. This research aims to systematically characterize and control the precipitation regime in advanced aluminum alloys. Unravelling the structure, topology, distribution, and crystallography of multi-scale precipitates in additively manufactured aluminum alloys is pivotal for controlling mechanical properties. Here, we present a correlative approach to characterize synergistic nanoprecipitates in an ultra-high-strength Zr-modified Al7075 alloy produced by laser powder bed fusion (LPBF). We integrate high-resolution transmission electron microscopy (HRTEM), scanning transmission electron microscopy (STEM), STEM energy-dispersive X-ray spectroscopy (STEM-EDX), nanobeam electron diffraction (NBED), and atom probe tomography (APT) to comprehensively resolve morphology, crystallography, chemical composition, and coherency/incoherency of the nanoprecipitates.
