The project goal is to extend application of the EBM and SLM techniques to new materials and applications – namely manufacturing of the difficult-to-build by AM precipitation hardening Ni-based superalloys for high-temperature applications in gas turbine components (Siemens Industrial Turbomachinery AB) and components for rocket engines (GKN Aerospace). Particular research focus will be placed on the importance of the base powder characteristics (powder size, morphology, rheology and especially surface chemistry) and its effect on AM manufacturing process and final component properties.
This will result in development of the knowledge base concerning required powder properties for the state-of-the-art and emerging AM applications. This is of strategic importance for the Swedish powder manufacturers to enter the fast-growing market of the materials for AM. Hence, a successful project execution will allow for development of base powder material as well as design and manufacturing strategies for AM fabrication of high-value components based on Ni-based superalloys.
