Abstract
AlSi10Mg alloy fabricated by Laser Powder Bed Fusion (LPBF) are extremely promising for the manufacture of precision and complex structural parts in aerospace on account of their low density, high specific strength, excellent corrosion and wear resistance and good processibility. However, LPBF additive manufacturing has led to anisotropy in the mechanical properties of as-printed AlSi10Mg alloy because of its complicated thermal-history, including directional heat input/conduction, repeated melting and rapid solidification. Although a great deal of work has been done in this research direction, there is still some disagreement. Therefore, to study the anisotropy of the tensile properties of LPBF-AlSi10Mg alloy, two kinds of tensile specimens built vertically and horizontally were designed, respectively. The influences of build orientation on the tensile properties of LPBF-AlSi10Mg alloy was investigated. The results show that the vertical specimen has a higher tensile strength, while the horizontal specimen shows a significant advantage in ductility.
