Powder feedstock production and 3D printing of refractory metals and alloys for aerospace applications - WReMo

Project summary

Additive manufacturing (AM) is currently the fastest developing production method. One of the AM’s problems is limited availability of feedstock powders, especially visible in the case of refractory metals. Refractory metal powder feedstock for AM is produced by plasma spheroidization or plasma atomization methods. In the scope of the project, W-Re and Mo-Re alloys will be developed, using both of those methods. Generic LPBF processing parameters for new feedstock material will be developed and demonstrative elements –rocket engine parts– will be manufactured. The new powders will be also developed with the use of material recovered from waste/scrap, which is especially important in case of materials regarded as Critical Raw Materials (CRM).The results of the project will form a basis of introduction of new products to the market and the project will help in gaining new knowledge on W-Re and Mo-Re alloys, as well as their behaviour during processing in plasma flame and LPBF processes
