Aluminium alloys have high specific stiffness, specific strength, corrosion resistance and machinability, making them highly desirable for lightweight applications in the automotive and aerospace industries. Additive manufacturing (AM) has recently expanded the potential for using aluminium alloys in safety–critical applications. However, AM introduces uncertainties that may impact mechanical properties, especially fracture behaviour. In this study, AlF357 was fabricated using Laser Beam Powder Bed Fusion (LPBF) in vertical and horizontal printing directions to assess their quasi-static tensile loading responses. Digital Image Correlation (DIC) is employed to estimate deformation parameters directly by measuring in-plane surface displacements near failure. The fractured surface was further characterized using scanning electron microscopy. It is observed that the horizontally printed ALF357 exhibits superior tensile properties as compared to the vertically printed samples.

摘要

Aluminium alloys have high specific stiffness, specific strength, corrosion resistance and machinability, making them highly desirable for lightweight applications in the automotive and aerospace industries. Additive manufacturing (AM) has recently expanded the potential for using aluminium alloys in safety–critical applications. However, AM introduces uncertainties that may impact mechanical properties, especially fracture behaviour. In this study, AlF357 was fabricated using Laser Beam Powder Bed Fusion (LPBF) in vertical and horizontal printing directions to assess their quasi-static tensile loading responses. Digital Image Correlation (DIC) is employed to estimate deformation parameters directly by measuring in-plane surface displacements near failure. The fractured surface was further characterized using scanning electron microscopy. It is observed that the horizontally printed ALF357 exhibits superior tensile properties as compared to the vertically printed samples.
