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. © 2020 The Authors.

Introduction Aluminum alloy AlSi10Mg is widely used for production of a broad variety of components due to its very good mechanical properties since decades. With the development of additive technologies, there has naturally been interest in the application of this alloy for production of complex shape components. In the last decade, a lot of attention has been paid to research on the relationship between mechanical properties, microstructure and laser powder bed fusion (L-PBF) process parameters of this hypoeutectic alloy, see e.g. papers by Zhao et al. (2022), Nicoletto (2020), Zhang et al. (2019) and Trevisan et al.
