Abstract: Aiming at the realisation of nuclear fusion reactors, the joining of W and steel parts is currently examined. Based on proposalsto implement functionally graded steel/W materials (FGMs) in the joint to cope with thermal stresses, the present contributionintroduces a novel fabrication method for steel/WFGMs. Electro Discharge Sintering (EDS) was used to consolidate Fe/Wpowderswithin milliseconds at atmosphere. Due to the short process time, the formation of detrimental intermetallic Fe-W precipitates islimited compared to established fabrication methods.The current work first presents results of the Fe/W powder processing, then a feasibility study regarding the fabrication ofhomogeneous and graded Fe/W composites with W volume fractions of 0, 25, 50 and 75 % via EDS is presented. Lastly, thecomposites are characterised microstructurally, thermo-physically, and mechanically in detail.
