Improvement of the NiTi actuator performance stability by decreasing its operating temperature range

The influence of fraction of the forward and reverse martensitic transformations on the variations in the recoverable strain, recovery stress, work output and irreversible strain was studied during thermal cycling of the equiatomic NiTi alloy under torque stress. The samples pre-deformed by various strain (3-7%) were subjected to thermal cycling in two regimes: in the temperature range of 450 K divided by T-c, where M-f

The influence of fraction of the forward and reverse martensitic transformations on the variations in the recoverable strain, recovery stress, work output and irreversible strain was studied. The equiatomic NiTi alloy was subjected to thermal cycling under torque stress and pre-deformed by various strain. The results showed that thermal cycling at different strains caused changes in these characteristic parameters.
