Applications

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 generated.

· 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

In 1989 a survey was conducted in the United States and Canada that involved seven organizations. The survey focused on predicting the future technology, market, and applications of SMA's. The companies predicted the following uses of nitinol in a decreasing order of importance: (1) Couplings, (2) Biomedical and medical, (3) Toys, demonstration, novelty items, (4) Actuators, (5) Heat Engines, (6) Sensors, (7) Cryogenically activated die and bubble memory sockets, and finally (8) lifting devices

Shape memory alloys are alloys with shape memory effect and are widely used as antennas for satellites and spacecraft. Automatic control switches for plumbing systems, fire doors and circuit outages, as well as medical materials such as orthodontics. For example, the antennas on satellites and spaceships are made of titanium-nickel shape memory alloys, which have a shape-memory function. First, the titanium-nickel alloy antenna is made into a parabolic surface, and then at low temperature to the antenna into a group, into a satellite or spacecraft cabin. When a satellite or spacecraft is launched and moved into normal and operational orbit, the antenna is automatically restored to its original parabolic shape when the temperature rises outside the cabin by sunlight.
