TL;DR: In this article, the authors show that porosity does not impinge on the high cycle fatigue properties when processing is kept within a ±30% tolerance band, and regardless of the processing condition, fatigue resistance follows a direct linear relationship with ductility and tensile strength in the low and high stress fatigue regimes respectively.

TL;DR: In this paper, the use of a neuro-fuzzy-based machine learning method for predicting the high cycle fatigue life of laser powder bed fusion stainless steel 316L was examined.

TL;DR: In this article, the microstructure-driven failure was modelled by a reference S-N curve where the intrinsic effect of micro-structure inhomogeneity was accounted for by applying a reduction factor on fatigue life.

TL;DR: In this article, the influence of build orientation and post-processing treatments (annealing or hot isostatic pressing) on the fatigue and fracture behaviors of L-PBF stainless steel 316L in the high cycle fatigue region was examined.

TL;DR: In this paper, the authors examined the monotonic and fatigue properties of as-built and heat-treated L-PBF stainless steel 316L. They found that the general linear relation σ f = mσ b for describing conventional ferrous materials is not applicable to L PBF parts because of the influence of porosity.
