Abstract Scope Powder bed fusion (PBF) techniques have the capability to produce complex near-net shaped components from a variety of different powders. For PBF of stainless steels it was suggested that the atomization gas and/or the background gas in the build chamber could have an important influence on the phase composition and microstructure in the as-built material. Since nitrogen is known to stabilize austenite, the use of nitrogen as the atomization gas or as the processing gas could affect the balance of the ferrite (⍺) and austenite (ɣ) phases. Here, we have built 17-4PH samples under identical conditions except for the use of N2 and Ar gas during the build process and we used commercial N2 and Ar gas-atomized powders. The effects of the gas on the microstructure, phase composition and final N2 contents have been assessed and the consequences of these observations can be a design variable in PBF of 17-4PH.
