Nickel-titanium alloy is a shape memory alloy. The memory alloy is a martensitic phase change alloy with very regular atomic arrangement and a volume of less than 0.5%. The amount of strain can be as high as 20%. After the stress is removed, the original shape can still be restored. This kind of deformation far beyond the elastic limit, the phenomenon that can still be restored is superelastic energy. This alloy will deform under the action of external force. When the external force is removed, it can restore its original shape under certain temperature conditions. Because it has more than one million recovery functions, it is called “memory alloy”. Nitinol shape memory alloy is a special alloy that can automatically restore its plastic deformation to its original shape at a certain temperature.
