Nitinol plate

Nickel Titanium (also known as Nitinol or NiTi) is in the unique class of shape memory alloys. A thermoelastic martensitic phase transformation in the material is responsible for its extraordinary properties. Nitinol alloys are typically made of 55%-56% Nickel and 44%-45% Titanium. Small changes in composition can significantly impact the properties of the material

4. Application:There are four commonly used types of applications for nitinol.

.Free Recovery: nitinol is deformed at a low temperature, and heated to recover its original shape.

.Constrained Recovery: The same, except that recovery is rigidly prevented, and thus a stress is generate..Work Production: Here the alloy is allowed to recover, but to do so it must act against a force (thus doing work).

.Superelasticity: As discussed above, here the nitinol acts as a super spring.
