-Shape memory

-Super elastic

The so-called superelasticity refers to the phenomenon that the strain generated by the sample under the action of external force is much greater than the elastic limit strain, and the strain will automatically recover during the unloading process. In the parent phase, due to the effect of external stress, the strain triggers the martensite transformation, so the alloy exhibits different mechanical properties from ordinary materials. Its elastic limit is much larger than ordinary materials. And it no longer follows Hooke& #39;s law. Compared with the shape memory effect, superelasticity does not involve heat.

A well-known computer manufacturer used Nitinol equipment to eject PCMCIA (International Personal Computer Memory Card Association) cards. In addition, Nitinol is also used to connect the end of the aircraft hydraulic tubing. In less severe applications, nitinol can bend the magic shop spoon when it is placed in hot water.
