Abstract
The effect of annealing temperature on shape memory properties of Ti50Ni25Cu25 melt-spun ribbons was studied by using differential scanning calorimetry (DSC) and thermomechanical analyzer (TMA). All the annealed ribbons had B19 structure at room temperature (RT) and B2 above 75 °C. They all showed a well-defined shape memory effect (SME) during thermal cycling from â40 to 120 °C. After annealing at 500 °C, the fully crystallized ribbon showed a shape recovery strain of 1.5% under 45 MPa. With the increase of annealing temperature the recovery strain decreased significantly.
