Call Impact Innovation: Feasibility studies within Technological Action Areas in the program Metals & Minerals

Purpose and goal

TILDA is a feasibility study with the purpose of investigating the possibility of defect-free additive manufacturing of advanced Ni-base superalloys for the following R&D project. TILDA aims to map possibilities of novel laser shaping technology in PBF-LB in combination with tailored metal powder and integrated HIP and heat treatment for defect-free fabrication of advanced Ni-base superalloys. This will provide the basis for a decision on the feasibility and scope of the full-scale R&D project.

Expected effects and result

TILDA will provide proof-of-concept enabling defect-free fabrication of advanced Ni-base superalloys using recent innovations along the whole PBF-LB manufacturing chain. TILDA will establish consortia possessing necessary know-how and infrastructure enabling further development and industrial utilization of project results. Successful execution of the concept in the frame of following R&D project will enable PBF-LB manufacturing of critical components for hydrogen fueled 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.
