TL;DR: In this paper, the microstructure and mechanical properties of 304 L stainless steel fabricated by selective laser melting are investigated, and a relative density of 99.9% is achieved with fine austenite grains and nanoscale cellular subgrains in size of approximately 0.5 µm.

TL;DR: In this article, two AlSi10Mg powder batches with satellite particles and non-satellite particles were used to fabricated LPBF samples, and the influences of the different powder properties on the defect, microstructure, and surface morphology were quantified.

TL;DR: In this paper, the authors measured the defect sinks of the laser powder bed bed fusion (LPBF) 304L stainless steel in as-built and solution-annealed conditions along with a conventionally rolled counterpart and found that the cellular sub-grains and dispersed nano-inclusions are the primary and secondary contributors to the helium resistance of LPBF 304L steel.

TL;DR: In this article, the correlation between the mechanical performance, which includes tensile and impact performance, and the microstructure of a SLMed 304L with a very low porosity in the solution annealed state was investigated.
