Abstract

Achieving guaranteed behavior after many years in the high temperature phase should consolidate the potential capability of SMA in damping of series of oscillation cycles followed by long periods of inactivity. To use an appropriate model in simulation of the material behavior they have been carried out three types of experimental analysis. The first one focuses on the remnant after quench effects. The second one centers on the parent phase and its time-temperature dependence. The third one shows the changes on transformation temperature and on hysteretic width related to the cycling and on the two-phase coexistence.
