Can metal remember its shape? 🖇️ Alex Dainis shows how a paperclip made out of nickel and titanium, also known as nitinol can be bent at room temperature, but when you add heat, it snaps back to its original shape because of a temperature-driven crystal structure change known as the shape memory effect. This material science can power everything from braces and eyeglass frames to life-saving medical devices. #ScienceExperiment #PhysicalScience #Science #Engineering #Chemistry | Museum of Scienc

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

Nitinol : Shape memory alloys Nickel titanium, also known as Nitinol, is a metal alloy of nickel and titanium, where the two elements are present in roughly equal atomic percentages. Different alloys are named according to the weight percentage of nickel, e.g. Nitinol 55 and Nitinol 60. Nitinol was developed by the U.S. Navy and stands for nickel titanium alloy. This metal is particularly useful for medical applications because it has thermal memory. This property allows stents to be made at a c
