HYdrogen-combustion improved PERformance systems enabled by Advanced Metal Powder processing - HYPER-AMP

Project summary

The transition to hydrogen-fuelled gas turbines requires materials and advanced manufacturing routes that ensure high performance and hydrogen tolerance under extreme thermal and chemical loads. Conventional fusion-based AM suffers from residual stresses, segregation, and cracking in high-γ′ Ni-based superalloys such as Alloy 247, limiting its use for critical components.
Objectives: Develop and validate sinter-based MIM and LMM processes for Alloy 247, with controlled debinding and sintering atmospheres, to achieve high density, stable γ/γ′ microstructures, and reliable high-temperature and hydrogen performance.
Potential applications: Small and medium turbine components, including fuel injectors, nozzles, and parts with internal cooling channels.
The project enables complex, high-performance, hydrogen-compatible components with reduced manufacturing waste, enhanced reliability, and lower environmental impact compared to conventional fusion-based AM.
