Impact Properties of SLM Printed Specimens from AlSi10Mg According to Building Orientation

Abstract:

This paper presents the dynamic impact properties of selective laser melted AlSi10Mg alloy Charpy test specimens under different building orientations. The study aimed to investigate the influence of dynamic properties on the building orientation, considering a good homogeneity in the microstructure of the specimens. The Charpy impact specimens were printed under the same laser velocity, energy density and gas flow for all four orientations. The experimental investigation was carried out on an Impact testing machine using a pendulum to determine the main mechanical and dynamic properties of the alloy. The results showed that the printing orientation has an extremely important role in terms of impact energy.
