Abstract
In the present work, effect of precipitation on two-way shape memory effect and deformation induced martensite stabilization of Ti50Ni25Cu25 ribbon was investigated. The two-way shape memory effect developed as a result of martensite deformation is affected by formation of precipitates. After straining martensite to 5.5%, a two-way shape memory strain of 1.25% was obtained in a sample annealed at 800 °C for 300 s that does not introduce B11 precipitates. Results also show that the deformed Ti50Ni25Cu25 ribbon containing precipitates has multiple-stage transformation characteristics during the first heating.
