WonderFacts. on Instagram: "Shape Memory Alloys (SMAs) are smart metals that can ‘remember’ their original shape. When deformed at a lower temperature, they seem to bend like ordinary metal—but once heated, their atomic structure realigns and they snap back to their original form. This unique property, called the shape memory effect, makes SMAs vital in fields like medicine (stents, dental wires), robotics (artificial muscles), and aerospace (self-repairing parts). A metal that literally remembe
