Development of an Alternative Heat Treatment to the Traditional T6 Heat Treatment of AlSi10Mg Alloy Produced by Additive Manufacturing

In this study, alternative solution heat treatments, applied at lower temperatures and shorter times, were applied to AlSI10Mg samples produced with the powder bed laser fusion technique. Thermocalc software was used to determine the temperatures of the NT6 solution heat treatment. The samples were analyzed by optical microscope, scanning electron microscope, energy-dispersive x-ray analysis, x-ray diffractometer and their mechanical behavior was examined. The results were compared with traditional T6 heat treatments and it was determined that the samples showed better ductility after NT6 heat treatments while maintaining the strength values in the traditional method.
