Abstract
The patterns of changes in microhardness and phase composition of Ni-Ti alloy in the austenitic structural-phase state have been experimentally studied depending on the fluence of irradiation with 84Kr15+ ions with the energy of 147 MeV. It was established that hardening with a maximum in the range of the projected range Rp and in the out-of-range region (h > Rp) increases with the growth of the irradiation fluence up to 5·1019 ion/m2. It was shown that the reason of hardening is formation of the radiation-introduced hardened defective structures. The formation of nano-sized particles of the martensitic R-phase and the decrease in NiTi phase content with the B2 structure are also characteristic in the process of irradiation up to maximum fluence due to radiation effects.
