The patterns of changes in microhardness and phase composition of Ni-Ti alloy in the martensitic-austenite state have been experimentally studied as a result of irradiation with 84 Kr 15+ ions with the energy of 93 and 147 MeV at the temperature of ≤ 100 °С. It was established that irrespective of the energy of 84 Kr 15+ ions, a complete radiationstimulated В19'→В2 transformation occurs during irradiation. It was shown that hardening of the modified layers increases with the energy of 84 Kr 15+ ions and it is determined by hardness of NiTi austenite phase due to formation of the hardened radiation-introduced defective structures.
