Description
Summary:[Display omitted] •Structure of the AlSi10MgCu(Zr, Ce) alloy in different thermal states.•Mechanical properties of the AlSi10MgCu(Zr, Ce) alloy in different thermal states.•Comparison of mechanical properties between Al-Si-Mg-(Cu) alloys was conducted. The article presents investigation of structure and mechanical properties of an advanced aluminum alloy Al-10Si-0.9Cu-0.7 Mg-0.3Zr-0.3Ce, produced by selective laser melting. By means of SEM, TEM and EDX-analysis some aspects of the alloy microstructure in as-built and thermal treated states are discussed. The alloy has high level of strength (UTS  > 390 MPa, YS  > 330 MPa) in T6-state, providing good elongation (El. > 6%). In annealed state the alloy also provides good combination of mechanical properties (UTS  > 350 MPa, YS  > 240 MPa, El. >  9%).
