Title Of Article :
EFFECT OF COOLING RATE ON THE SHAPE MEMORY BEHAVIOR OF Ti-54at.%Ni ALLOYS
Abstract :
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.
