Nitinol is a metal that can remember its original shape when heated. This metal has been useful in the medical and space fields. #Engineering | Interesting Engineering

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
