Microstructural and mechanical aspects of AlSi7Mg0.6 alloy related to scanning strategies in L-PBF

AlSi7Mg0.6 alloy is the most widely used cast for aerospace and automotive applications. Therefore, it essential to explore effect of scanning strategy parameters on final part properties in laser powder bed fusion (L-PBF) process. The stripes chessboard strategies such as stripe length, rotation angle, island size mechanical microstructural L-PBF processed studied. evolution residual stresses also investigated longitudinal transverse directions. Cooling rates are estimated using cell within melt pool. Three distinct regions (i.e., fine, coarse, heat-affected zone) pool corresponding different cooling could be identified based Si morphology. texture material can tailored by changing strategies. This study comprehensively presents results concerning porosity, properties, crystallographic texture, rates, grain morphology, additively manufactured alloy.
