Deterioration of EUROFER plates by severe bending

Many components of the blanket box for a future fusion power plant are fabricated of curved EUROFER plates with cooling channels. The bending process causes an investigation of the expected material deterioration. The present paper focuses on the deterioration results caused by a cold bending process of a solid tin as a first approach to such a technology. Two possible countermeasures against this deterioration have been taken and checked as an important request of this paper. The results are showing the feasibility of a bent procedure for a U shaped cooling plate of a breeder unit.
