TED-Ed: Magical metals, how shape memory alloys work - Ainissa Ramirez

The video explores shape memory alloys, metals that can remember and return to specific shapes when heated. It explains the atomic structure and phase changes that enable this behavior. A demonstration with a nickel-titanium wire shows how heat can change its shape. The video also highlights applications of these alloys, such as in the Mars Rover, medical stents, robotics, and even bras, showcasing their versatility and impact on technology and daily life.
