| Abstract: | Cu-base shape memory aloy(SMA) is one of SMA which possesses bright future of industrial use. But its shape memory capacity easily degrades during thermal cycling, and so it hinders the alloy putting into practical use.The stability of CuZnAl SMA coil-spring actuators was studied, and the reasons of the degradation of shape memory capacity were analyzed by means of optical microscopy, X-ray diffraction and TEM in this paper. |
