The current investigation shows the feasibility of 316L steel powder production via three different argon gas atomisation routes (closed coupled atomisation, free fall with and without hot gas), along subsequent sample by laser bed fusion (PBF-LB). Here, a mixture pure Fe atomised is used for PBF-LB to induce chemical composition gradient in microstructure. Optical microscopy μ-CT investigation...
