The TWSM strain of the snap-acting element made of Ni51Ti49 alloy finishes abruptly at certain temperature without any additional mechanism, within an interval less than 1 ms. A thermodynamic model is presented to account for these observations.展开更多

文摘Snap-acting transformation and snap-acting two way shape memory (TWSM) effect have been obtained in NiTi alloy using the constrained effect of stress on the driving force of TWSM element. The TWSM strain of the snap-acting element made of Ni51Ti49 alloy finishes abruptly at certain temperature without any additional mechanism, within an interval less than 1 ms. A thermodynamic model is presented to account for these observations.
