“…Due to its mechanical properties, long-term stability and predictability up to ∼650 • C, the reduced activation ferritic-martensitic EUROFER 97 steel is being considered for structural applications in the breeding blankets of ITER, and for the demonstration fusion reactor DEMO [1,2]. The strength of this steel can be enhanced by precipitation hardening, and strengthening induced by dislocations, particle dispersion or grain boundaries.…”

Abstract:The EUROFER 97 steel was processed by equal channel angular pressing (ECAP) at 550 • C for four passes via route C. The starting material consisted of ferrite-martensite dual phase composed by small subgrains of about 0.5 m and low angle boundaries less than 5 • . The volume fraction of second phase particles was around 10 vol.%, besides a texture formed by several fibers orientations belonging to the zone axes 110 , 111 and 112 . Increasing ECAP deformation, this microstructure became into equiaxed grain structures of less than 1 m, and the misorientation between contiguous grains increased. This refine-ment of the microstructure was accompanied by the development of a new texture described by a family of fiber orientations related by rotations around axes 110 and 111 . Tensile tests have revealed that an ECAP treatment at 550 • C for two passes could significantly strengthen the tempered material still maintaining good ductility.

“…The ESR-produced ingot was forged to square bar shaped slabs with 400 mm × 150 mm cross-section. Plates of F82H with various thicknesses (15-90 mm) were fabricated from forged F82H-BA07 [4]. The detailed evaluation of F82H-BA07 heat was started on mechanical properties such as tensile, Charpy impact, fatigue, and creep properties.…”
