Abstract
Heat treatments commonly used for post-processing in additive manufacturing (AM) deal with relieving residual stresses. However, generally these treatments reduce strength properties of material such as yield stress (YS) or ultimate tensile strength (UTS). This paper is aimed at finding of the optimal heat treatment for additively manufactured parts made of aluminum alloy AlSi10Mg. Different heat treatments are compared. Positive effect of solution treatment with quenching and artificial aging on strength properties with simultaneous induction of compressive residual stress in top surface of specimens is shown.
