Considered in this paper is the effect of electron irradiation on the phasestructural
state and micromechanical characteristics of reactively- and nonreactivelypressed
TiB2–TiС composite ceramic materials. It is shown that reactively-pressed
specimens after irradiation demonstrate a growing tendency to phase formation, which
considerably affects proceeding of relaxation processes in them. This special feature of
reactively-pressed ceramics can improve radiation resistance of construction materials.
