Title: Response of isotopically tailored titanium diboride to neutron irradiation

Abstract

The response of polycrystalline TiB 2 to neutron irradiation was investigated. The material was fabricated using isotopically enriched 11B powders to minimize helium production via the 10B(n, α) 7Li reaction. Neutron irradiation was conducted at temperatures of ~200°C and ~600°C to a fast fluence of 2.4 × 10 25 n/m 2 (>0.1 MeV). The material exhibited some swelling, but less swelling at the higher irradiation temperature. No macroscopic damage was observed in the irradiated material, although moderate irradiation–induced micro–cracking was found in the irradiated TiB 2. Furthermore, this study demonstrated improved radiation resistance of isotopically tailored TiB 2 compared with natural boron TiB 2, which exhibited macroscopic fracture by irradiation.
