Pagination or Media Count:
The reversion stress of NiTi is characterized under several unique thermomechanical situations. The effect of partial reversion of initial strain on the reversion stress is studied. The final stress is apparently not dependent on whether the initial strain is lost by stress-free reversion or stress-reversion. The effect of developed stress on the temperature range for the reversion transformation to austenite is also studied. A model for the mechanism of constant-stress reversion is proposed.
