 Shape-memory material

Shape-memory materials are special types of materials that have the ability to return to a predetermined shape when subjected to an external stimulus, such as heat or stress. These materials usually undergo a phase transformation that allows them to "remember" their original configuration. ### Types of Shape-Memory Materials: 1. **Shape-Memory Alloys (SMAs):** - These are metallic alloys, such as nickel-titanium (NiTi), that exhibit shape-memory properties.
