There are four commonly used types of applications for nitinol.

A major limitation to further use of nitinol has been its difficulty to weld, both to itself and other materials.

In the past ten years, laser welding nitinol to itself has become a relatively routine process.

Orthodontists are now using nitinol on the wires and springs in braces.

This causes the nitinol to contract back to its original shape, applying a constant force to move the teeth.

In order for nitinol to have the desired superelastic and shape memory properties, heat treatment is required.

The combination of heat treatment and cold working is essential in controlling the properties of nitinol.

Fatigue failures of nitinol devices are a constant subject of discussion.

Surface passivation techniques can greatly increase the corrosion resistance of nitinol.

The hysteresis width depends on the precise nitinol composition and processing.

In this case, as soon as the stress is removed, the nitinol will spontaneously return to its original shape.

The presented specifications are typical for commercially available shape memory nitinol alloys.

Worked on the project of shape memory alloy named "Nitinol" to obtain the first woven fabric.

Indeed, the relatively high cost of nitinol has led some manufacturers to use cheaper, copper-based alloys.

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

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

It includes experiments with electricity, electronics, and nitinol.

Heat treating nitinol is delicate and critical.

There is a great deal of effort underway trying to better understand and define the durability limits of nitinol.

While the potential applications for nitinol were realized immediately, practical efforts to commercialize the alloy did not take place until a decade later.

Demonstration model heat engines have been built which use nitinol wire to produce mechanical energy from hot and cold heat sources.

Nanomuscle cannot hope to replace all such motors, however, because nitinol cannot cycle fast enough to move anything more than a few times per second.

One often-encountered complication regarding nitinol is the so-called R-phase.

It has been repeatedly shown that nitinol releases nickel at a slower pace than stainless steel, for example.

All metals contain inclusions, and nitinol cannot be melted without inclusions-they are omnipresent.
