Influence of the temperature of high-energy krypton ion implantation of the structure and properties of a Ni-Ti alloy
The influence of the temperature of implantation of a Ti-Ni shape-memory alloy with 84Kr15+ ions at the energy E = 147 MeV on its structural-phase state is investigated. At the implantation temperatures 250 and 300 °С in the region of the projective ion range Rp and beyond the following phenomena are revealed: re-formation of the В 19 ' martensitic phase, formation of nanosized particles of the R -phase, increased electrical conductivity due to the formation of radiation-defect structures, strengthening of the alloy in its austenitic structural-phase state, and an increase in the temperature intervals of the latter.
