The name of this material derives from its composition (nickel and titanium) and the place of its discovery (the Naval Ordnance Laboratory). While smart materials are modern materials, ... Nickel titanium (nitinol) is a type of SMA, and it contracts when heated, whereas most metals expand. Thanks to its moderate solubility range, its composition can be changed, and it can be alloyed with other elements to alter … Shape memory refers to the ability of Nitinol to undergo deformation at one temperature, then recover its original, under formed shape upon heating above its transformation temperature. NDC is one of the leading manufacturer and supplier of this metal alloy. However, when a small current is passed through the wire it returns to a much harder form and to its original length with a reasonable force. While smart materials are modern materials, ...
