摘要：
We have revealed and investigated the burst character of shape-memory deformation (SMD) in crystals of Cu-13.6 wt % Al-4.0 wt % Ni alloys. We have found that, after giving SMD to 8% when compressed in the direction of the [100] axis and subsequent heating on the solid base with an additional weight of 400 g, the system can rebound up to a height of 55 mm at a speed of ≈1 m/s. The calculations showed that, in the absence of load, a crystal with a weight of 0.8 g (in on absence of air friction) can rebound to a height of 27.5 m with a velocity of 23 m/s when rising from the base. The mechanism of such an unusual behavior of shape-memory deformation in this alloy was studied.
