Nitinol memory wire Facts... - Metallurgical engineering

Nitinol Paperclip: nitinol is a special alloy of nickel and titanium that can be trained to a specific shape at high temperature- in this case the shape of a paperclip. Bend it up at room temperature and it will always snap back into shape when exposed to moderate heat (such as hot tea water). This remarkable property is a type of solid state reversible phase transition known as a martensitic transformation. This sample of nitinol wire came to me in my latest @thecuriositybox which never fails t
