Within the chemical industry and in contrast to conventional manufacturing processes, Laser Powder Bed Fusion (LPBF) of Alloy 400 opens up for functional components that withstand harsh environments. On the basis of a holistic process route, the present work focusses on modifying the chemical composition of the base material with Titanium in order to allow the formation of TiN nanoparticles during powder production and LPBF, respectively, as well as documenting their influence on the mechanical properties. Parameter optimization for gas atomization and LPBF is carried out and the microstructure of both powders and parts is examined. It was found that besides Cu segregations on grain boundaries and dislocation formation on cell walls, TiN successfully formed in both powders and parts. The Ti-enriched parts resulted in enhanced mechanical properties in terms of hardness, tensile and creep due to these homogeneously distributed dispersoids. Hence, nanoparticle integration proved to be feasible and effective for the present alloy system.
