Spark Plasma Sintering (SPS) is a promising technology for the fabrication of structural materials for fusion reactors. In particular it has emerged as a potential alternative for the fabrication of Oxide-Dispersion Strengthened Ferritic Steels, which are candidate materials for the future DEMO fusion reactor.
Researchers from the CINN in collaboration with colleagues from CEIT-IK4 have studied the effect of the SPS sintering process on the microstructure of ferritic steels with oxide nanoparticles. The challenge was to increase the density of dislocations, preferred nucleation sites, and enhance the precipitation of oxide nanoparticles.
A poster summarizing the results of the research with the title “Microstructural comparison of Oxide-Dispersion Strengthened Ferritic Steels produced by HIP and SPS” will be presented at the 30th Symposium on Fusion Technology (SOFT 2018).
