Shape-memory alloys are materials that can be deformed in cold but go back to their original shape when you heat them | Interesting Engineering

Shape memory materials are fascinating substances that can return to their original shape after being bent or stretched, triggered by heat or pressure. The most common kind, known as shape memory alloys (like Nitinol), can “remember” their original form at the molecular level. When deformed, they hold that shape until heated, when their internal structure shifts back and restores them to their preset design. These materials are used in fields like medicine, aerospace, robotics, and even in flexi
