The effect of thermal cycling on electrical properties of Ti-49.8%Ni alloy pre-deformed by rolling at 500ºС was studied. It was shown that the number of cycles, i.e., the number of phase transformations, during thermal cycling can strongly affect the temperature dependences of electricity. Generation of dislocations during phase transitions leads to increase of electrical resistance of the alloy and stabilization of B19'-phase in austenite matrix. The electricity of the material does not change upon further cycling after the dislocation density saturates to a certain value.
