How does nitinol work?


Nitinol Shape Memory Alloys undergo a phase transformation in their crystal structure when cooled from the stronger, high
temperature from (Austenite) to the weaker, low temperature from (Martensite). This inherent phase transformation is the basis for
the unique properties of these alloys - in particular, Shape Memory and Superelasticity.


Shape Memory
When shape memory alloys are in their martensitic form, they are easily deformed to a new shape. However, when the alloy is heated
through its transformation temperatures, it reverts to austenite and recovers its previous shape with great force. This process is knows as Shape Memory. The temperature at which the alloy remembers its high temperature from when heated can be adjusted by slight changes in alloy composition and through heat treatment. In the Nickel Titanium alloys, for instance, it can be changed from above +100 deg. C to below -100 deg. C. The shape recovery process occurs over arange of just a few degrees and the start or finish of the transformation can be controlled to within a degree or two if necessary.


Super-elasticity


These unique shape memory alloys also show a Superelastic behavior if deformed at a temperature which is slightly above their
transformation temperatures. This effect is caused by the stress-induced formation of some martensite above its normal
temperature. Because it has been formed above its normal temperature, the martensite reverts immediately to undeformed austenite
as soon as the stress is removed. This process provides a very springy, "rubberlike" elasticity in these alloys.

Product application


1. Nitinol spring: nitinol push and pull spring is a kind of spring used for orthodontic treatment. It has the characteristics of nitinol super elasticity, and is suitable for orthodontic treatment, opening up the space between teeth and pulling teeth in different directions. A force of about 50 g can be produced by extending the NiTi coil spring by 1 mm. NiTi coil spring has high elastic properties, which can produce soft and stable continuous force under tensile state. The force attenuation is very small, which can produce ideal orthodontic force for clinical tooth movement. Meet the physiological requirements. Compared with the stainless steel wire of the same diameter, the force released by the Ni Ti wire spring is 3.5-4 times lower. Therefore, in the application of orthodontic treatment, patients not only have mild pain, soft and lasting feeling power, but also reduce the return visit time, shorten the course of treatment and improve the curative effect. It is a new excellent mechanical device in orthodontic treatment.

2. Because of the super elasticity, shape memory and low stress-strain curve of nitinol archwire, nitinol archwire is usually used as the initial archwire in orthodontic treatment system. In this way, the discomfort of patients will be greatly reduced. Because there are several kinds of straight wire orthodontic techniques, mbt technique recommends the use of 0.016 inch heat activated nickel titanium alloy arch wire (hant wire), demon self-locking bracket technique recommends the use of copper containing heat activated nickel titanium alloy arch wire (phase transition temperature is about 40 ℃), 0.016 inch super elastic Ni Ti alloy arch wire is recommended for early alignment in o-pak.
