SiC ceramics are promising candidate materials for future advanced nuclear energy system, due to the uniqueproperties such as superior high temperature mechanical properties, high temperature chemical inertness and lowneutron capture cross section[1;2]. Furthermore, some transition metals such as Fe, Co and Ni could be introducedinto SiC so that the material obtained magnetic properties[3] and could be conveniently driven by the electromagneticforce. Compared with Co and Ni, Fe owns the lowest neutron capture cross section. In view of this consideration,the metal matrix composite SiC-Fe was designed.
