Summary:Title screen
The effect of irradiation with 141 MeV and 231 MeV xenon ions and irradiation temperatures T = 100 and 250 °C on the structural-phase state and properties of titanium nickelide in its initial martensitic-austenitic and austenitic states was experimentally studied. The radiation effects revealed are as follows: changed phase composition caused by B19? > B2, B2 > R transformations and recovery of the martensitic phase B19? at 250 °C; increased nanohardness, microhardness and electrical resistance at 100 °C due to formation of track nanostructures and radiation-induced defects; radiation-induced accumulation of xenon in the near-surface layer. In addition, softening of the near-surface area and decreased electrical resistance were found for the martensitic-austenitic state at irradiation temperature of 250 °C, which was caused by the changed content of the Ni-Ti phase with the B2 phase and R phase.
