| Abstract |
The strain-resistivity behavior of Ti-45.0Ni-%.0Cu wires has been measured during
superelastic cycling. The results are in good agreement with previous results, showing that the main changes of resistivity during superelastic cycling are due to Austenite ↔ Martensite phase changes and anisotropic variant orientation. The true plastic strain (dislocations) does not seem to play an important role for this alloy. |
