The effect of heat treatment (at a temperature slightly below the eutectic one) on the microstructure, phase composition, and mechanical properties of the additively manufactured AlSi10Mg alloy (fabricated by selective laser melting—SLM) and its cast counterpart (CT) is analysed. The cast and additively manufactured samples are annealed at 520°C for 6 hours with subsequent furnace cooling, and for 1.5 hours with quenching in water followed by natural or artificial ageing at 150°C for 10 hours. The results demonstrate significant changes in the microstructure (e.g., size and morphology of the eutectic silicon phase), phase composition, and the evolution of mechanical properties in heat-treated materials compared to those manufactured additively and by casting. Moreover, the microstructure and micromechanical properties of the materials are largely dependent on the manufacturing technology—casting or additive manufacturing. The mentioned heat-treatment regimes and cooling conditions (furnace, quenching, air) directly affect the morphology of eutectic silicon and the number of reinforcing phases, namely, Mg2Si, Al15(Fe,Mn)3Si2, FeAl3Si2, both in the cast and additively manufactured materials. Starting from a continuous network of eutectic Si, fragmentation occurs, forming inclusions of various geometries with subsequent spheroidization of these inclusions. Si particles in the heat-treated SLM alloy are smaller and more spheroidized in comparison with those in the heat-treated cast material. The results of this study allow for controlling the mechanical properties of AlSi10Mg alloy by selecting the manufacturing technology and appropriate heat-treatment regime. For the SLM sample in its initial state, the highest microhardness value is of 1.38 GPa, which decreases to 0.55 GPa after annealing and increases to 1.12 GPa after quenching and artificial ageing. For the CT alloy, the initial microhardness value of 0.76 GPa decreases initially slightly to 0.74 GPa after similar treatment regimes and, then, increases to 1.08 GPa.

Key words: AlSi10Mg, additive manufacturing, selective laser melting, casting production, heat treatment, microstructure, phase composition, mechanical properties.
