摘要：
The influence of long-term storage of TiNi-based and CuZnAl alloys on their functional properties was investigated. It was established that during 30 years’ storage of TiNiFe thermomechanical couplings, the stresses in them practically did not decrease. Couplings with CuZnAl alloy sleeves during storage weakened slightly. The one-way shape memory effect in equiatomic TiNi alloy did not change after 25 years. It was found that the value of two-way shape memory effect in the first cycle after storage at room temperature in martensitic state for more than 15 years was higher than before storage.
