For certain solid-state additively manufactured processes, more attention is being given to the initial mechanical properties of feedstock powder as they play a role in determining the final properties of the deposit. To quantify the mechanical properties of the powder, and therefore predict the performance of the consolidated material, a predictive strength model is being developed that considers strengthening contributions from solid solution, precipitation, and microstructure. The results of the additive strength model are experimentally verified for several aluminum alloys including Al 2024, 5056, 6061, and 7075. Characterization techniques including scanning and transmission electron microscopy, x-ray diffraction, and differential scanning calorimetry are utilized.
