The effects of cooling rate after
aging at 550 °C for 3 h on the shape memory behavior and mechanical properties
of Ti-54at.%Ni alloys are investigated in compression. It was found that it is
possible to tailor the transformation temperatures of Ti-54at.%Ni alloys with
cooling rate where multiple step transformation can also be observed. Shape
memory behavior with transformation strain of 1 % is observed under ultra high
stress level of 1500 MPa. It is also found that shape memory effect is highly
stress dependent.
