Abstract

We report here on results obtained by training NiTi of different compositions and submitted to different thermomechanical treatments in order to develop a device working exploiting the TWSME (two way shaoe memory effect). DSC measurements performed on the starting material allowed to assess the different response to the training procedure of the different materials used. Some evaluation on the stability on short term cycling of the material both in wire and strip shape was done.
The calorimetric evaluation was performed on the trained nad cycled material as weel. This allowed to asses the general effect on the microstructrure of the procedure performed. The results are here discussed at the light of the potential use of these training procedures in a real device.
