Abstract

In this study, AlSi10Mg samples produced by the direct metal laser sintering (DMLS) method were applied to heat treatment with different parameters (stress relief and T6). Heat-treated and as-built samples were subjected to intergranular corrosion test according to BS EN ISO 11846 standard. Hardness, tensile, electrical conductivity, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and weight loss tests were applied to the samples. The corrosion, electrical conductivity, and mechanical properties of the DMLS-AlSi10Mg material were investigated in detail depending on the heat-treatment parameters.
