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/mm(3).　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　per-formance　was　determined　against　SiC　balls.　It　was　found　that　the　sample　fabricated　with　VEDs　of　67　J/mm(3)　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.
