Abstract Scope |
Alloy 400 is a widely used material being known for its excellent corrosive resistance. 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. Parameter optimization for gas atomization and LPBF is carried out and the microstructure of both powders and parts is examined. It was found that TiN nanoparticles were present along the entire manufacturing process. TiN-enhanced parts resulted in superior mechanical properties due to these fine dispersoids. Hence, nanoparticle integration proved to be feasible and effective for the present alloy system. |
