The alloys: 45 at % Ti-45 at % Ni-10 at % Nb (1) and 42,6 at % Ti-46,5 at % Ni-8,0 at % Nb-2,9 at % Zr (2), which are used for thermomechanical couplings (TMC) were investigated. It was shown that high-temperature thermomechanical treatment (HTMT) at 800 deg C, epsilon=0,3 creating dynamically polyg...
