Original title: How much do you know about such a great nickel-titanium alloy? NiTi alloy is a kind of shape memory alloy. Shape memory alloy is a special alloy which can automatically restore its original shape at a specific temperature after plastic deformation. Its expansion ratio is more than 20%, its fatigue life is up to the seventh power of 1 × 10, its damping characteristic is 10 times higher than that of ordinary springs, and its induced phase transformation process in NiTi alloys. 2. Hyperelasticity: The so-called hyperelasticity refers to the phenomenon that the sample produces a strain far greater than the elastic limit strain under the action of external force, and the strain can be automatically restored when unloaded. That is to say, nickel titanium wire , in the parent phase state, due to the external stress, the stress-induced martensite transformation occurs, so the alloy shows different mechanical behavior from ordinary materials, its elastic limit is far greater than that of ordinary materials, and it no longer obeys Hooke's law.

Corrosion resistance: Studies have shown that the corrosion resistance of nickel-titanium wire is similar to thatuation experiment of different archwires, it is found that the vibration amplitude of stainless steel wire is larger than that of superelastic nickel-titanium wire, and the initial vibration amplitude of superelastic nickel-titanium archwire is only half of that of stainless steel wire. The good vibration and shock absorption characteristics of archwires are very important for the health of teeth,nickel titanium wire, while traditional archwires, such as stainless steel wires, tend to aggravate root resorption.
