Nickel-Titanium, often referred to as NiTi, is a unique alloy composed of nickel and titanium. It is known for its remarkable ability to undergo significant deformation and return to its original shape when heated. This property is called shape memory effect, making it useful in various applications, including medical devices and robotics. In addition to the shape memory effect, Nickel-Titanium exhibits superelasticity, allowing it to stretch and bend without permanent deformation at certain temperatures. These characteristics make NiTi valuable in fields such as orthodontics, where it is used in dental braces, and in the aerospace industry for components that require flexibility and resilience.
