Shape-memory coupling

Shape-memory coupling is a concept often related to materials science and engineering, particularly concerning shape-memory alloys (SMAs) and their coupling with other mechanisms or systems, such as actuation and control applications. In the context of shape-memory alloys, these materials can undergo phase transformations that allow them to "remember" a specific shape. When deformed at a lower temperature, they can return to their original, pre-deformed shape upon heating to a certain temperature (the transformation temperature).
