Abstract
This work proposes a hardness-strength correlation model for aged laser powder bed fused Al-Mg-Zr alloy, enabling strength estimations based on microhardness data. Such a correlation could streamline property assessments for complex geometries in AM alloys. Additionally, this study examines the material's micromechanical properties, including plasticity and work-hardening behavior, linking these characteristics to tensile performance and microstructural attributes. To this end, depth-sensing nanoindentation and microhardness testing were used to establish a correlation between hardness and tensile properties, offering a rapid and cost-effective approach for assessing material performance. Besides, microstructural analysis via scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD) revealed a bimodal grain distribution, comprising ultrafine grains (<2 µm) and coarser grains (<5 µm), with precipitates observed within and along grain boundaries. Transmission electron microscopy (TEM) confirmed nanoscale L1₂-Al₃Zr precipitates in various morphologies (cuboidal, spherical, and filamentary) that contribute to strength enhancement through grain refinement and solid solution strengthening from Mg and Mn.
