| description | The phase composition, microstructure, and multiple shape memory effect of TiNi<sub>50−x</sub>V<sub>x</sub> alloys were studied in this work. The phase composition of the TiNi<sub>50−x</sub>V<sub>x</sub> system is the TiNi matrix, spherical particles of TiNiV, the secondary phase Ti<sub>2</sub>Ni(V). Doping of TiNi alloys with vanadium atoms leads to an increase in the stability of high-temperature B2 and rhombohedral R-phases. An increase in the atomic volume with an increase in the concentration of the alloying element V from 1 to 4 at.% was established. Vanadium doping of the Ti–Ni–V system alloys leads to an increase in the temperature interval for the manifestation of the multiple shape memory effect. It has been established that the value of the reversible deformation of the multiple shape memory effect both during heating and during cooling increases linearly from 2 to 4% with an increase in the vanadium concentration. |
