Tailored microstructure control by Additive Manufacturing as enabler for green hydrogen fueled gas turbines (TILDA2)
Purpose and goal
Future carbon-free power generation requires ramping of hydrogen capability in gas turbines. Burning hydrogen gas faces a lot of challenges connected to high temperatures. Project is aiming to develop PBF-LB processing using novel laser shaping technology in combination with tailored metal powder and integrated HIP and heat treatment to enable tailored microstructure control and defect-free fabrication of advanced Ni-base superalloys, required for application in hydrogen fueled gas turbines.
Expected effects and result
TILDA will enable defect-free fabrication of advanced Ni-base superalloys using recent innovations along the whole additive manufacturing chain. Successful project execution will revolutionize additive manufacturing of non-weldable materials by enabling cost-effective additive manufacturing of components with complex geometries, high strength and oxidation resistance for demanding applications required for green hydrogen-powered gas turbines.
Planned approach and implementation
TILDA will implement a comprehensive approach by combining recent advances in tailored alloy design and recent developments in PBF-LB processing and post-AM HIP and heat treatment. Project involves optimization of the powder material for AM,integration of latest developments in laser technology in PBF-LB, including advanced laser beam shaping and laser scanning, novel integrated HIP and heat treatment processing, followed by microstructure and material properties characterization.
