摘要：

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%). (c) 2020 Elsevier B.V. All rights reserved.
