摘要：

The microstructure and mechanical properties of AlSi10Mg alloy fabricated by selective laser melting were systematically investigated in this study. Substantial hardening of this alloy was achieved by aging heat treat-ment. The alloy exhibits an excellent combination of strength and ductility, attributed to its fine cellular structure with nanoscale needle-like precipitates.
