This alloy remembers its shape, and what's your superpower? More about nitinol: http://bit.ly/2rl0PrD | MEL Science

Nitinol is a unique alloy made of nickel and titanium that exhibits one of the most remarkable behaviors in materials science. Its defining feature is shape memory, the ability to be deformed at one temperature and then return to a preset shape when heated. This transformation comes from a reversible shift between two crystal structures known as martensite and austenite. The change occurs with precision and reliability, giving nitinol an almost lifelike response to temperature. Another important

Shape Memory Alloys (SMAs) are a special class of metal alloys, like Nitinol, that can be bent and deformed when cold, but snap back to a programmed shape when heated. From a physics perspective, this happens because of a solid-state phase transformation between two crystal structures: martensite (soft) and austenite (rigid). When the alloy is cold, it enters the martensite phase: flexible, low-symmetry structure that allows bending without permanent atomic rearrangement. When heated, it transit
