Design and fabrication of a Sustainable high temperature resistant steel by Directed Energy Deposition based on laser and metallic powders


  • Start: 01/09/2023
  • End: 01/08/2026


The DESI-DED project is part of a global project, coordinated by CENIM-CSIC and participated by CIEMAT and the Carlos III University which its main objective is to design and manufacture, using different additive manufacturing technologies, a ferritic-martensitic steel, suitable for use in high-temperature parts due to its excellent microstructural stability and creep behaviour, which will improve the efficiency of power generation plants. The objective of AIMEN will be to optimise the parameters and methodology of manufacturing by direct energy laser and powder deposition (DED-LB/Mp) to obtain ferritic-martensitic steel parts with optimal properties and free of defects that meet the standards associated with this alloy. The results are compared with those obtained by the other technologies, laser powder bed fusion (LPBF) and composite extrusion modelling (CEM), establishing a pre-normative framework to compare the microstructures obtained by the three methods that will allow the qualification of this material in the future.
