摘要：

The effect of annealing temperature on shape memory properties of Ti50M15Cu25 melt-spun ribbons was studied by using differential scanning calorimetry (DSC) and thermomechanical analyzer (TMA). All the annealed ribbons had B 19 structure at room temperature (RT) and B2 above 75 degrees C. They all showed a well-defined shape memory effect (SME) during thermal cycling from -40 to 120 degrees C. After annealing at 500 degrees 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. (c) 2004 Elsevier B.V. All rights reserved.
