Investigation of mechanical properties of AlSi10Mg alloy produced by metal additive manufacturing method

Additive Manufacturing (AM) technology is a revolutionary technology that enables the production of parts with complex geometries that are lightweight yet offer high specific strength. In this study, mechanical properties, tensile tests and hardness measurements of parts prodeced by powder bed fusion method in accordance with ASTM E8M standard in different construction directions (horizontal, angular and vertical) were investigated. Macroscopic and microscopic observations were carried out to understand the deformation mechanism. As a result; in the samples obtained from AlSi10Mg material produced by DMLS method, three parameters such as layer thickness (mm), laser power (W), laser irradiation time (m) and energy density (J/mm³) for the DMLS process were obtained. The samples were produced using the Additive Manufacturing method. When the microstructure, hardness and FESEM (field emission scanning electron microscope) images of AiSi10Mg samples produced with different parameters by the DMLS method were examined, a high strength and ductile structure was observed in the horizontal sample, while a harder structure was detected in the angled sample. In the vertical sample, similar features were analyzed compared to others.
