| Abstract Scope |
In this work, we have developed a high-performance Al-Mg-Mn-Sc-Zr alloy optimised for Laser Powder Bed Fusion (LPBF) using our innovative precipitate strengthening factor, which is built on the competition between the nucleation and growth of kinetics for precipitation. The alloy features a hierarchically heterogeneous microstructure with a triple-modal grain distribution and nano-precipitates. The uneven distribution of L12-ordered Al3(Sc, Zr) nanoparticles contributes to this unique structure. The mechanical properties are tunable through direct ageing, and the highest yield strength reaches 649.6 MPa, making it a promising candidate for complex-shaped, high-strength, and ductile components in advanced structural applications. This work advances the potential for near-net shape forming of aluminium alloy components, meeting critical industry needs for high-performance materials in additive manufacturing. |
