In contrast to casting, laser powder bed fusion (LPBF) enables high cooling rates across the whole transverse section. In this study, the effect of processing parameters on the microstructure and compression behavior of Al₉₂Mn₆Ce₂ was investigated and compared to the results of as-cast counterparts. The hierarchical microstructure of the LPBF specimens was identified by SEM, EBSD, and TEM. Intermediate volumetric energy inputs (< 45 J/mm³) led to a high amount and strong refinement of the intermetallic, non-equilibrium Al₂₀Mn₂Ce phase and, thus, to a pronounced tolerable compressive stress (> 1200 MPa). Additionally, we investigated the influence of baseplate heating (up to 300°C) to reduce residual stresses. The preheating allowed the fabrication of crack-free and scaled-up geometries (e.g. edge lengths > 45 mm). However, the heat impact led to an increased residual porosity (> 3%), a coarsened microstructure, and additional intermetallic phases. In summary, the results indicate a high sensitivity of Al₉₂Mn₆Ce₂ to hot tearing, pore and phase formation, and thus the mechanical response. We reported on our process optimization approach and the advantages of LPBF with its high intrinsic cooling rates, making the aforementioned alloy attractive for lightweight applications.
