Notch Orientation and Fatigue Strength of As-built L-PBF AlSi10Mg
Procedia Structural Integrity(2022)
摘要
Fatigue life of AlSi10Mg specimens with semi-circular notch manufactured by Laser Powder Bed Fusion was experimentally determined. The fatigue life in the high cycle fatigue region is strongly influenced by the microstructure, the as-built surface quality of the notch root, both of which depend on the notch orientation with respect to the build direction and by residual stresses.
