Abstract

This study aimed to develop a high-strength, low-cost AlMg10ScZr alloy with a higher Mg content and lower Sc content than the Al–Mg–Sc–Zr alloy, which is reported to have high strength. A Powder bed fusion process was employed with various volumetric energy density (V_ED) to establish the optimum process conditions. It was found that with increasing volumetric energy density, the elongation and ultimate tensile strength increased. In addition, it was possible to obtain a sound specimen at a lower V_ED through preheating of the build plate, confirming that the process efficiency was increased. These enhanced mechanical properties are attributed to an increase in relative density. At a volumetric energy density of 209.9 J mm⁻³ with the build plate heated to 180 °C, the best combination of the ultimate tensile strength (529.6 MPa) and elongation (17.3%) was achieved.
