用TAQ 800动态力学分析仪研究了退火对镍钛丝回复应力的影响。结果表明，在350-600°C范围内，回复应力随退火温度的升高而减小;在600-900°C范围内，回复应力随退火温度的升高而增大。结果表明，在室温下，恢复应力与平台应力成正比，零载荷和相对温度下的可恢复应变在As以上增加。
The effect of annealing on the recovery stress of Ni–Ti wire has been studied by using a dynamic mechanical analyzer (DMA), TAQ800. The results show that the recovery stresses decrease with increasing annealing temperature in the range of 350–600°C and increase with increasing annealing temperature in the range of 600–900°C. It was found that the recovery stress is proportional to the plateau stress at room temperature, the recoverable strain under zero load and relative temperature increase above As.
