| Abstract Scope |
Aluminum (Al) alloys have broad industrial applications. However, most commercial high-strength Al alloys are not suitable for additive manufacturing due to their high susceptibility to solidification cracking. In this work, a custom Al alloy was fabricated by selective laser melting. Nanoprecipitates form in the as-printed Al alloy. Macroscale compression tests reveal a combination of high strength, over 700 MPa, and prominent plastic deformability. Micropillar compression tests display significant back stress in the alloys. Post-deformation TEM analyses reveal deformation mechanisms in the high-strength Al alloys. This study shows that proper introduction of heterogeneous microstructures and nanoscale precipitates may lead to the design of strong, deformable Al alloys via additive manufacturing. |
