Inadequate wear and corrosion resistance limit the use of the Sc- and Zr-modified Al-Mg alloys. In this study, X-ray diffraction was employed to determine the phases present in an AlMgScZrMn alloy fabricated by laser powder bed fusion (L-PBF) at volumetric energy densities (VEDs) from 52 to 102 J/mm3. Microstructural characterization was performed using a combination of electron backscattered diffraction analysis and optical microscopy. The corrosion resistance was determined using electrochemical measurements in a 3.5 wt% NaCl solution. The hardness and the Young's modulus were determined from nanoindentation tests. The wear performance was determined against SiC balls. It was found that the sample fabricated with VEDs of 67 J/mm3 exhibited the best wear resistance. Higher hardness and finer grain size help to improve the wear resistance of AlMgScZrMn alloys. The increase in large angle grain boundaries leads to higher corrosion susceptibility, resulting in faster corrosion rates. This work provides a basis to enhance the service stability of AlMgScZrMn alloys. •High density AlMgScZrMn components were successfully fabricated by L-PBF under different VEDs ranges.•The addition of Zr achieves an effective grain refinement for the primary Al alloy.•The increase in HAGBs leads to higher corrosion susceptibility, resulting in faster corrosion rates.•The AlMgScZrMn fabricated with 67 J/mm3 presented the highest nano hardness and the lowest wear rate.
