| Abstract Scope |
The objective of this study is to investigated the influence of crystallographic texture on the mechanical properties of AlSi10Mg specimens fabricated by Laser Powder Bed Fusion (LPBF). In order to generate different crystallographic textures, the laser scanning strategy was modified. Electron Backscatter Diffraction (EBSD) and X-Ray diffraction (XRD) were used to analyze the crystallographic texture. It was shown that a variation of the laser scanning strategy can be successfully apply to produce different crystallographic textures, including nearly complete (001) textures. Subsequent to the sample fabrication mechanical test were performed. The results show that the different crystallographic textures result in direction-dependent properties, including stiffness, strength, and notably, fatigue resistance. The presented approach demonstrates the potential to deliberately tailor mechanical properties through process-controlled microstructure orientation and residual stress engineering. |
