Evaluation / Assessment of Thermal Properties of NITI

Nickel titanium, also known as nitinol (part of shape memory alloy), is a metal alloy of nickel and titanium, where the two elements are present in roughly equal atomic percentages. Nickel containing alloys are present in a substantial amount and in wide range of appliances and auxiliaries and utilities used in orthodontics and are hence an integral part of every orthodontic intervention. Nickel titanium is a base metal alloy used in orthodontics. Niti arch wires have two remarkable properties, namely shape memory and super elasticity, which helps in achieving Nitinol alloys exhibit two closely related and unique properties: shape memory effect (SME) and super elasticity (SE; also called pseudo elasticity, PE).
