Özet
In this study, AlSi10Mg samples were produced using the Powder Bed Laser Fusion (PBLF) method with standard parameters. Specimens were retrogression and re-aging (RRA) heat-treated at various conditions. The effects of the RRA heat treatments on the properties of PBLF parts were examined by microstructure, electrical conductivity, and electrochemical corrosion tests. Microstructural properties were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy-dispersive X-ray (EDS) analysis. The results showed that after RRA heat treatment, the electrical conductivity of the material decreased slightly, and the corrosion resistance increased.
